Half of the formic acid solution is neutralised on addition of KOH solution to it. If `K_(a)" of " HCOOH" of " 2 xx 10^(-4)`. Then find pH of the solution.

pH of 10^-6 N KOH solution is

An acid solution of pH 6 is diluted 100 times . The pH of solution .

The pH of 10^-4 M KOH solution will be

A bufer solution was prepared by dissolving 0.05 mol formic acid & 0.06 mol sodium formate in enough water to make 1.0 L of solution. Ka for formic acid is 1.80 xx 10^(-4) Calculate the pH of the solution.

An acid solution of pH =6 is diluted 100 times. The pH of solution becomes

An acid solution of pH =6 is diluted 100 times. The pH of solution becomes
