How is the concentration of hydronium ions `(H_(3)O^(+)`) affected when a solution of an acid is diluted?

How is the concentration of hydroxide ions ( OH^(-) ) affected when excess base is dissolved in a solution of sodium hydroxide?

The solution which tends to keep the concentration of hydrogen ions constant even when small amount of strong acid or strong base are added to them, is known as

A dilute solution of ethanoic acid in water is called

Consider the following statements : a. The hydronium ion (H_(3)O^(+)) is the strongest acid that can exist in aqueous solution . b. Mixing concentrated acid or bases with water is a highly endothermic reaction . Which of these statement (s) is / are correct ?

The concentration of H^+ ions in a solution whose pH is 8

What is a concentrated and dilute solution?

A reaction is first order in A and second order in B. i) Write the differential rate equation ii) How is the rate affected on increasing the concentrations of B there times ? iii) How is the rate effected when the concentrations of both A and B are doubled ?

The first ionization constant of H_(2)S is 9.1xx10^(-8) . Calculate the concentration of HS^(-) ion in its 0.1M solution. How will this concentration be affected if the solution is 0.1M in HCl also ? If the second dissociation constant of H_(2)S is 1.2xx10^(-13) , calculate the concentration of S^(2-) under both conditions.

By which scale concentration of hydrogen ion in a solution is measured ?
