Question

Plz help !!
Chemistry .
Class 10 Acids Bases and Salts .

Plz give explanation for your choice .

Answer 1

Hi.

Here is your answer---

_____________________

Solution P has a ph of 13
Thus, It is Basic(Alkaline) in nature.

Solution Q has a ph of 6
Thus, It is Slightly Acidic in nature.

Solution R has a ph of 2
Thus it is Highly Acidic in nature.

Now, Solving the Given Questions,

(a) Answer--- Solution P
     Reason---Ammonia gas in produced when an ammonium salt(Such an Ammonium Sulphate or Ammonium Chloride) reacts with base. For example--- When Ammonium Sulphate is treated with Calcium Hydroxide(Which is Basic in Nature) in a laboratory, Ammonia gas in produced. 

(b) Answer---Solution R 
     Reason---Acidic Character Increases as the ph decreases, thus Solution R has a less ph as a result of which it is an strong Acid.

(c) Answer---Solution Q
  Reason---Solution Q has a ph of 6, i.e. it is weak acid(As the ph increases,Acidic Character decreases and vice-versa), thus it do not ionize completely in water.Therefore, it contains both ions and molecules in a solution.
