Anonymous users2024-02-061.The alkali solution interacts with the acid-base indicator to change the color of the acid-base indicator;
The purple litmus test solution turned blue, and the colorless phenolphthalein test solution turned red.
2.Alkaline solutions can react with carbon dioxide to form salts and water;
For example: Ca(OH)2+CO2=CaCO3 +H2O3Alkali can react with acid, which neutralizes the base to produce salt and water;
2naoh+h2so4=na2so4+2h2o4.Alkali can metabolize with salt;
For example: agno3+hcl=agcl +hno3 hope to help the landlord!

Anonymous users2024-02-05The basic salt we call is a salt in which the anions generated during ionization include hydroxide ions in addition to acid ions, and the cations are metal ions (or ammonium ions).
As for the writing of the chemical formula, it depends on what kind of basic salt it is, taking several common basic carbonates as examples:
The chemical formula of basic magnesium chloride is: mg(OH)Cl,
The chemical formula of basic copper carbonate is: Cu2(OH)2CO3

Anonymous users2024-02-04Take basic copper carbonate as an example: Cu2(OH)2CO3 is also written Cu(OH)2·CuCO3

If the landlord still has questions, he can continue Zhu Wen. The satisfaction of the landlord is the motivation for me to answer the question, thank you.
It should be (2*28): 44
It can be considered that if you want to contain the same mass of oxygen elements, (because they are the same elements), so you have to have the same number of oxygen atoms, then 2 CO molecules contain as many O atoms as 1 CO2 molecule, so the quantity ratio of CO and CO2 is 2:1, so the mass ratio is equal to the ratio of quantity multiplied by molecular weight, that is, 56:44, which is further simplified to 14:11 >>>More
There are a lot of documents to find, all formats are available, very complete. The above point is everything, you go and see it, it's very good.
When elements are combined with each other, the ratio of the number of reactant atoms is not fixed, but is determined by the number of electrons in the outermost shell of the atom. For example, a sodium ion (valency of +1, loss of an electron) must be combined with a chloride ion (valency of -1, gain an electron). And one magnesium ion (valency of +2, loss of two electrons) must be combined with two chloride ions. >>>More
