You dissolve NH&CN in water. Will the resulting solution be acidic or basic? You need to explain your answer using the appropriate Ka and Kb values. OR you can show your calculations!

NH₄CN is a salt formed from weak base NH₄OH and weak acid HCN so that it undergoes complete hydrolysis

The hydrolysis process is a term used for the reaction of substances with water

There are 3 types of hydrolysis salts

1.Salt from strong acids and strong bases does not undergo hydrolysis so that the pH of the neutral solution = 7

2.Salt from strong acids and weak bases (pH <7) or from strong bases and weak acids (pH> 7) will be partially / partially hydrolyzed

3.Salt from weak acids and weak bases (pH depends on the value of Ka and Kb) will be completely hydrolyzed

NH₄CN is a salt formed from weak base NH₄OH and weak acid HCN so that it undergoes complete hydrolysis

NH₄OH + HCN⇒NH₄CN+H₂O

Can be formulated :

Ka> Kb then [H +]> 7 and pH <7 ⇒ acidic

Ka <Kb then [H +] <7 or pH> 7 ⇒alkaline

Ka = Kb then pH = 7 ⇒neutral

let that person have a turn to speak : )

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
