pH of acid solution is always ……………..than 7.

pH of a basic solution is always more than that of an acidic solution solution of same concentration.

Ph of an acidic solution is:

pH of 10^-6 N KOH solution is

Fill ups pH of acids is …………….than 7 while that of bases is …………..than 7.

If ph value of solution is less than 7, then what does it indicate?

Improper fraction is always less than 1

If ph value of a solution is more than7, then what does it indicate?

Acid-base indicators are either weak organic acids or weak organic bases. Indicator change colour in dilute solution when the hydonium ion concentration reaches a particular calur For example. Phenolphthalein is a coloureless stbstance in any aqueous solution with a pH less than 8.3 In between the pH range 8.3 to 10, transition of colour (colourless to pink ) takes place and if pH of solution is greater than 10 solution is dark pink. Considering an acid indicator Hln, the equilibrium involving it and its conjgate base In^(-) can be represented as : " " underset("acidic from")(HIn)hArrH^(+)underset("basic from")(In^(-)) pH of solution can be computed as : " " pH=pK_(In)+log.([IN^(-)])/([HIn]) In general, transition of colour takes place in between the pH range pK_(In+-1.
