How is the concentration of hydroxide ions (OH – ) affected when excess base is dissolved in a solution of sodium hydroxide?
Answer:
Hydroxide ions (OH – ) are formed by dissociation of the base. As the amount of NaOH increases, dissociation of ions increase and more hydroxide ions (OH – ) are produced.
Hence, the concentration of hydroxide ions (OH – ) increases and the basicity of a solution increases as well.
