Question

Скласти молекулярні, повні та скорочені іонні рівняння гідролізу солей по стадіям KNO2

Answer 1

Molecular Equation for the Hydrolysis of KNO2

The molecular equation for the hydrolysis of KNO2 can be written as follows:

KNO2 + H2O → KOH + HNO2

Complete Ionic Equation for the Hydrolysis of KNO2

The complete ionic equation for the hydrolysis of KNO2 can be obtained by separating all the ions present in the reaction. In this case, the potassium ion (K+) and the nitrite ion (NO2-) are the ions involved. The equation can be written as follows:

K+ + NO2- + H2O → KOH + HNO2

Net Ionic Equation for the Hydrolysis of KNO2

To obtain the net ionic equation, we remove the spectator ions, which are the ions that appear on both sides of the equation and do not participate in the reaction. In this case, the potassium ion (K+) is a spectator ion. Therefore, the net ionic equation for the hydrolysis of KNO2 is:

NO2- + H2O → KOH + HNO2

Please note that the hydrolysis of KNO2 results in the formation of potassium hydroxide (KOH) and nitrous acid (HNO2).
