To a 10 ml of `10^(-3)` N `H_2SO_4` solution water has been added to make the total volume of 1 L. Its pOH would be

To a 10mL of 10^(-3) N H_(2)SO_(4) solution water has been to make the total volume of one litre. Its pOH would be :

22.7 mL of (N/10) Na_(2)CO_(3) solution neutralises 10.2 mL of a dilute H_(2)SO_(4) solution. The volume of water that must be added to 400 mL of this H_(2)SO_(4) solution in order to make it exactly N/10.

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) If this solution were diluted to 10 times its volume, what would be the pH ?

4.0 g of monobasic, saturated carboxylic acid is dissolved in 100 mL water and its 10 mL portion required 8.0 mL 0.27 M NaOH to reach the equivalence point. In an another experiment, 5.0 g of the same acid is burnt completely and CO_(2) produced is absorbed completely in 500 mL of a 2.0 N NaOH solution. A 10 mL portion of the resulting solution is treated with excess of BaCl_(2) to precipitate all carbonate and finally titrated with 0.5 N H_(2)SO_(4) solution. Determine the volume of the acid solution that would be required to make this solution neutral.

1 mol of C_(6)H_(6) , 0.1 mol of HNO_(3) and 0.05 mol of H_(2)SO_(4) are mixed and water is added to the mixture . pH of the solution , if the final volume is 1 L , is
