NaOH is a strong base. An aqueous solution is made containing 0.300mol.dm^-3 of NaOH at room temperature. Calculate the pH of this solution.

Concentration of NaOH=Concentration of OH- ions (NaOH is a strong base)

Kw=1x10^-14 (at room temperature/25 degrees)

using Kw=[H+][OH-]

We can figure out the [...

How will the position of equilibrium shift for an endothermic reaction when heated?

The position of equilibrium will shift to the right, favouring the forward reaction, to oppose the increase in temperature. Endothermic reactions absorb heat and therefore if the endothermic reaction i...
