`25 mL` of `0.50M H_(2)O_(2)` solution is added to `50 mL` of `0.20 M KMnO_(4)` is acid solution. Which of the following statements is true?

20mL of H_(2)O_(2) solution is reacted with 80 mL of 0.05 M KMnO_(4) "in acidic medium then what is the volume strength of" H_(2)O_(2) ?

The volume of 0.1M H_(2)SO_(4) solution required to neutralise 50ml of 0.2M NaOH solution is -

50 mL of H_(2)O is added to 50 mL of 1 xx 10^(-3)M barium hydroxide solution. What is the pH of the resulting solution?

50 mL of H_(2)O is added to 50 mL of 1 xx 10^(-3)M barium hydroxide solution. What is the pH of the resulting solution?

50 ml of 0.2 M HCl is added to 30 ml of 0.1 MKOH solution. Find the pH of the solution.

A solution of H_(2)O_(2) labelled as '20 V' was left open. Due to this some, H_(2)O_(2) decomposed and volume strength of the solution decreased . To determine the new volume strength of the H_(2)O_(2) solution, 10 mL of the solution was taken and it was diluted to 100 mL . 10 mL of this diluted solution was titrated against 25 mL of 0.0245 M KMnO_(4) solution under acidic condition. Calculate the volume strength of the H_(2)O_(2) solution .
