If 100 mL of 0.1 M $\rm{HNO_3}$ is mixed with 50 mL of 0.1 M $\rm{NaOH}$, what will be the resulting pH?

Which of the following has ${P^H}$ is equal to near about one

Buffer capacity of a buffer solution is x, the volume of 1M added to 100 ml of this solution if the change of ${P^H}$ by 1 is

One litre of water contains ${10^{ - 7}}\;{\rm{mole}}\;{{\rm{H}}^ + }$ ions. Degree of ionisation of water is:

$100\;{\rm{ }}mL\;{\rm{ }}of\;{\rm{ }}0.01{\rm{ }}M$ solution of ${\rm{NaOH}}$ is diluted to $1\;{\rm{d}}{{\rm{m}}^3}$. What is the pH of the diluted solution?

$0.1\;{\rm{millimole}}$ of ${\rm{CdS}}{{\rm{O}}_4}$ are present in $10\;{\rm{mL}}$ acid solution of $0.08\;N\;{\rm{HCl}}{\rm{.}}$ Now ${{\rm{H}}_2}{\rm{S}}$ is passed to precipitate all the ${\rm{C}}{{\rm{d}}^{2 + }}$ ions. The ${\rm{pH}}$ of the solution after filtering off precipitate, boiling of ${{\rm{H}}_2}{\rm{S}}$ and making the solution $100\;{\rm{mL}}$ by adding ${{\rm{H}}_2}O$ is:
