Saonification happens when a fatty acid is reacted with NaOH.
We can assume the copper wire has reacted completely with excess sulfur being burned off when there is no longer any traces of yellow color sulfur in the crucible.
A pH indicator: the color is changed at the end of the reaction, when the solution become alkaline.
Hydrochloric acid (HCl) is a strong acid, and when reacted with a strong base will give a neutral salt. When reacted with a weak base it will give an acid salt. Example, HCl + NH3 => NH4Cl.Carbonic acid (H2CO3) is a weak acid and is actually CO2 + H2O. When reacted with a strong base, it will give an alkaline salt and when reacted with a weak base will give a solution the pH of which will depend on the Kb and Ka of the reactants.
Carbonic Acid is water reacted with carbon dioxide.
Carbonic Acid is water reacted with carbon dioxide.
Hydrogen will be liberated.
Substances which are reacted with Sulphuric acid tend to produce sulphates.
no idea
hydrochloric acid and sodium hydroxide
Copper does not react with dilute Sulphuric acid.
Na2So4
