Find the pH of resultant solution when 100 mL of 0.005 M H_(2)SO_(4)"

1.	Find the pH of resultant solution when 100 mL of 0.005 M H_(2)SO_(4)" at " 25^(@)C is diluted to 100 mL. What is the amount of NaOH required to be dissolved in 500 mL to exactly neutralise the above solution ?
Answer» Solution :(i) calculation of `H^(+)` ion CONCENTRATION in the diluted solution (ii) calculation of the number of moles of hydrogen ions present in 100 mL of 0.005 M `H_(2)SO_(4)` (iii) calculation of the concentration of the hydrogen ions of `H_(2)SO_(4)` solution after dilution (IV) calculation of the number of moles of NAOH required to neutralise the above solution (v) calculation of the amount of NaOH required (VI) `4 XX 10^(-2) g`
