Hi People ,
I had a problem solving this question,could you please help me:D
The question:
a)The ionisation constant for propanoic acid is 1.26x10^-5 mol dm^-3.Calculate pH of a 1.0M solution
b)What is the hydroxide ion concentration of this solution?
c)Pocroc acid has an ionisation constant of 5.0x10^-3 mol dm^-3. It can act as an acid base indicator,the anions being red,and the free acid yellow.What colour will it show in a solution of pH 5?
