Will potassium sulfate be obtained after evaporation of potassium hydroxide and sodium sulfate solut

No. Potassium hydroxide and sodium sulfate solution cannot metacompose reaction.

The essence of the metathesis reaction is that the two substances that undergo the metathesis reaction exchange ions with each other in the aqueous solution, and combine into substances that are difficult to ionize--- precipitation, gas, and water, so that the ion concentration in the solution decreases, and the chemical reaction is carried out in the direction of the reduction of ion concentration.

The conditions under which the metathesis reaction occurs.

Basic oxide + acid – salt + water.

One of them is soluble).

Alkali + acid --- salt + water.

One of them is soluble).

The type of metathesis reaction is salt (dissolved in water or dissolved in acid) + acid – new salt + new acid or water or gas).

Salt (soluble) + base (soluble) - new salt + new base at least one is precipitate).

Salt (soluble) + salt (soluble) – two new salts.

One of them is precipitation).

Conditions for metathesis reaction to occur: (the following conditions are met at the same time) 1) reactants: must be soluble (including soluble acids).

2) Product: precipitation, gas or water generation.

Let me say that after closed evaporation and drying, it is generated: potassium hydroxide, sodium sulfate, sodium hydroxide, potassium sulfate. Metathesis reflection tells us that these two substances do not react and also tells us that they are in the form of ions in solution.

This is the process of evaporation, where the particles are randomly combined with each other. So there should be four products.

No. Because potassium hydroxide does not react with sodium sulfate (no gas, water, precipitation, that is, substances that are difficult to ionize), potassium sulfate is naturally not formed.

Sodium thiosulfate (Na2S2O3) is soluble in leaky water but does not tolerate high temperatures. Therefore, dissolving sodium thiosulfate in distilled water and then heating and boiling it may cause sodium thiosulfate to decompose and lose its effect.

On the other hand, sodium thiosulfate can already be completely dissolved in water at room temperature, and there is no need to dissolve it in distilled water beforehand. In addition, when sodium thiosulfate is used in conjunction with some oxidizing agents, it needs to be mixed in a specific order and ratio to avoid unnecessary chemical reactions. Therefore, before using sodium thiosulfate, you should carefully read the product manual or related experimental methods and use it as required.

In conclusion, whether sodium thiosulfate can be dissolved in distilled water first, or when it can be added to the reaction, needs to be considered on a case-by-case basis and specific chemical reaction to ensure the success and safety of chemical experiments.

Sodium bisulfate reacts with potassium hydroxide to form sodium sulfate, potassium sulfate, and water.

Summary. The chemical formula of the reaction of potassium persulfate and sodium sulfide is K2S2O8 Na2S K2So4 Na2So4. This is a redox reaction in which potassium persulfate (K2S2O8) acts as an oxidizing agent to oxidize sulfur ions in sodium sulfide (Na2S) and convert them into sulfate ions, while potassium persulfate is reduced to potassium sulfate (K2SO4).

The products of the reaction are potassium sulfate and sodium sulfate (Na2SO4), two inorganic salts that are common chemicals and are commonly used in chemical experiments and production. This reaction is also used industrially in the preparation of pulp bleach, dyes, pharmaceuticals, etc. That's all for me.

I'm still a little confused, can you be more detailed?

I'm sorry I don't understand, but can you elaborate on that?

This happens because:1The chemical reaction is affected by the temperature, too high the state temperature will accelerate the reaction, too low the temperature will slow down the reaction, and the temperature of the normal temperature reaction is generally around 25, if the temperature is too low, the reaction will slow down or even not happen.

2.Chemical reactions are affected by oxygen, which can accelerate reactions, and if there is not enough oxygen, the reactions will slow down or even not happen. Workaround:

1.The reaction temperature is increased to more than 25 to accelerate the reaction. 2.

The oxygen in the reaction vessel is increased to speed up the reaction. Personal Tips:1

When carrying out chemical reactions, it is necessary to pay attention to the influence of temperature and oxygen to ensure the normal progress of the reaction. 2.In the laboratory, it is important to be safe and not to set the temperature too high to avoid accidents.

Under strong alkalinity, 2kmNO4 K2SO3 2KOH——2K2MNO4 K2SO4 H2O,K2MNO4 is a green masking solution; Then, because of the consumption of KOH, it becomes a reaction of 2kmNO4 3K2SO3 H2O-2MWo2 (precipitation) and 3K2SO4 2KOH under weak alkalineness

Therefore, under alkaline conditions, potassium permanganate foci are not brothers.

React with sodium sulfite, the solution is dark green, and then turbid light brown.

Sodium sulfite has a high melting point, and it will not decompose or hydrolyze when it is evaporated

Na2SO3 + H2O = = = 2NaOH + SO2, while sulfur dioxide in turn will be reabsorbed by sodium hydroxide and therefore will not be hydrolyzed. Sodium sulfite, on the other hand, is reducible and reacts with O2 when heated: 2Na2SO3 + O2===2Na2SO4 to form sodium sulfate.

Got it?

Can sulfites heated in H2O be oxidized directly to sulfate?

The answer is: it is feasible to evaporate and dry in an evaporation dish.

For example: 1. The solubility of potassium nitrate is determined at room temperature by evaporation dish evaporation.

2. When separating the mixture of potassium nitrate and sodium chloride, first configure their mixed solution, concentrate it by evaporation, and when the temperature is 119 °C, the sodium chloride crystallization is precipitated. The mother liquor after the separation of sodium chloride is slowly cooled, and the potassium nitrate is crystallized and precipitated. The product is filtered, washed and dried.

As long as the temperature is well controlled, it is perfectly fine (use a thermometer and do not heat the temperature above the melting point of potassium nitrate). It's just that the concentrated solution reacts too violently and is not very safe.

You can use an evaporation dish to evaporate and dry, and the temperature is well controlled. The normal synthesis method for purification is basically the evaporation and drying method.
