Q)You are provided with aqueous solution of KNO 3 , Na 2 CO 3 and ZnSO 4 . Arrange them in increasing order
of pH.
Answers
Answer:
HCl>CH3COOH>H2O [Acidic strength]. How satisfied are you with the answer? This will help us to improve better.
on the basis of increasing order , we will get namely
ZNSO4 <KNO3 < Na2Co3.
This happen as follows, as we already know that all those aqueous solution which below 7 on PH scale are considered acidic in nature and those which above 7 are basice in nature and those which are at 7 on this scale are neutral. keeping all the above statements in mind and ATQ , ZNSO4 solution will be lowest value on this scale because it is acidic in nature ,KNO3 is neutral because it is made up of a strong acid (nitric acid) and a strong base named potassium and NA2CO3 has a highest value on PH scale,it's measure is above 7 on this scale because it is basic in nature.
I hope, this will be banifical for all of you.
