Why doesn t salt react with silicic acid, sodium silicate and hydrochloric acid reaction equation?

It is a general rule for strong acids to make weak acids.

You can add it to the reaction, and that will produce hydrochloric acid and sodium silicate.

But hydrochloric acid is much more acidic than silicic acid.

Therefore, it will react back quickly and produce sodium chloride and silicic acid.

The final is equivalent to ... No response.

The rule of acid-base reaction is that strong acid replaces weak acid, and if NaCl reacts with silicic acid, HCL and NaSiO3 are generated, which produces stronger acids and bases than reactants, which does not meet the rule of strong acid replacing weak acid.

From the perspective of metathesis reaction, the main component of table salt is NaCl, and if it reacts with silicic acid, it is weak acid to strong acid, and weak acid to strong acid in chemistry is just that!

The ion equation for the reaction of sodium silicate and hydrochloric acid is: SiO3 2- +2H+ = H2SiO3. Sodium silicate is commonly known as bubble alkali in life, and its aqueous solution is commonly known as water glass, which is a condition adhesive and has a very wide range of uses.

The larger the modulus of sodium silicate, the more difficult it is for solid sodium silicate to dissolve in water, n is 1 can be dissolved in warm water, n needs hot water to dissolve, n is greater than 3 needs more than 4 atmospheres of steam to dissolve. The larger the sodium silicate modulus, the more Si content, the increase of sodium silicate viscosity, easy decomposition and hardening, and the increase of adhesion, and the degree of polymerization of sodium silicate in different modulus is different, which leads to the impact on the production and application of its hydrolysate products.

Uses of sodium silicate1. Sodium silicate is used as iron flocculant and alum coagulant in sewage treatment plants.

2. It is used as a fixative for manual dyeing.

3. Used for pottery.

4. Widely used in food preservation, home brewing and aquaculture.

5. Mainly used for detergent, paper, water treatment and building materials.

6. One of the biggest uses of sodium silicate solution is as cement for the manufacture of cardboard. If used as paper glue, the sodium silicate seams have a tendency to gradually crack after a few years, and the paper surfaces no longer stick together.

The reaction equation of sodium silicate and hydrochloric acid is: Na Sio +2HCl=2NaCl+H2SiO.

Because silicic acid is a solid that is insoluble in water, it precipitates. The larger the modulus, the more difficult it is for solid sodium silicate to dissolve in water, n is 1 can be dissolved in warm water, n is increased by hot water to dissolve, n is greater than 3 and needs 4 atmospheres to defeat the steam on the town to dissolve. The larger the sodium silicate modulus, the more silicon oxide content, the increase of sodium silicate viscosity, and the increase of adhesion, so the orange judgment of sodium silicate with different modulus has different uses.

Sodium silicate

Sodium silicate is the most valuable filler in the soap industry, and the incorporation of sodium silicate into the laundry soap can buffer the alkalinity of the laundry soap, reduce the loss of the laundry soap in water, and enhance the washing ability and prevent the rancidity of the soap; Sodium silicate plays a role in synthetic detergents to help wash and wither, prevent corrosion, and stabilize foam; It can be used as a filler for papermaking; It is used in the manufacture of silicone gel and silica gel.

Solid-state Na2O·NSIo2 is an intermediate product with a mostly light blue appearance. Na2O·NSi2 molded by dry casting is block and transparent, while Na2O·NSi2 molded by wet water quenching is granular and converted into liquid Na2O·NSI2 before it can be used. Common Na2O·NSI2 solid products are:

Bulk solids, powdered solids, instant sodium silicate, sodium metasilicate zero water, sodium metasilicate pentahydrate.

Sodium silicate (Na2SiO3) reacts with hydrochloric acid (HCl) because hydrochloric acid is a strong acid, while sodium silicate is an alkaline salt. In aqueous solution, hydrochloric acid releases H+ ions, while sodium silicate releases Na+ and SiO3 2- ions.

The reaction equation is as follows:

na2sio3 + 2hcl → 2nacl + h2o + sio2

In this reaction, the H+ ions in hydrochloric acid react with the SiO3 2- ions in sodium silicate to form water and silicon dioxide (SiO2). At the same time, sodium chloride (NaCl) is also generated.

This reaction is an acid-base neutralization reaction, through the neutralization of acids and bases, water and salts are produced. Among them, silica is solid, insoluble in water, and will exist in solution in the form of suspended solids.

It should be noted that this reaction is exothermic and will be accompanied by exothermic phenomena. In practice, attention should be paid to controlling the reaction conditions to avoid dangerous substances or adverse reactions.

Sodium silicate and hydrochloric acid will undergo a neutralization reaction to form silicic acid and sodium chloride.

The chemical equation is as follows:

Na2SiO3 + 2HCl H2SiO3 + 2NaClIn the reaction, sodium silicate (Na2SiO3) and hydrochloric acid (HCl) react to form silicic acid (H2SiO3) and sodium chloride (NaCl). Silicic acid is a weak acid that can be further broken down into water and silica. Sodium chloride is a common table salt.

It is important to note that when performing this reaction, care should be taken to ensure operational safety and proper laboratory protocols should be followed.

There is no direct reaction between sodium silicate (Na2SiO3) and hydrochloric acid (HCl). Sodium silicate is an alkaline salt, while hydrochloric acid is an acid that undergoes a neutralization reaction in water.

The correct reaction equation should be:

na2sio3 + 2hcl + h2o → 2nacl + h4sio4

In this reaction, sodium silicate reacts with hydrochloric acid to form sodium chloride (NaCl) and silicic acid (H4SiO4). Silicone is a weak acid that partially dissociates in water.

It should be noted that this chaotic reaction is an exothermic reaction, which will be accompanied by an exothermic phenomenon. In practice, attention should be paid to controlling the reaction conditions to avoid dangerous substances or adverse reactions caused by imitation silver. For the reaction of sodium silicate and hydrochloric acid, it is best to conduct experimental testing and risk assessment in the laboratory.

1) Sodium silicate and sodium bisulfate are bright and funny!

2) Equation: Na2SiO3 + 2NaHSO4 = H2SiO3 + 2Na2SO4

or Na2SiO3 + 2NaHSO4 + H2O = H4SiO4 + 2Na2SO4

Of course, silicic acid with sodium hydroxide.

The reaction produces sodium silicate.

and water. 2NaOH + H2SiO3 === Na2SiO3 + 2H2O This is a typical neutralization reaction.

However, unlike other neutralization reactions, silicic acid is slightly soluble, so the reaction speed is relatively slow. Because, in other neutralization reactions, acids are soluble, under such conditions, that is, jujube early alkali insoluble with water, acid-base can still undergo neutralization reaction.

The colloid is first polymerized and precipitated to produce silicic acid precipitation, and then reacts with it to generate Na2SiO3 solution.

Or sodium silicate.

2NaOH+H2SiO3==Na2SiO3H2O silicate ions are very easy to bind to H+

Therefore, the silicate, the silicic acid is not acidic, and the salt is changed.
