Hi there!
Henderson's equation for pH of a buffer solution is given as,
pH = pKa + log [salt] / [acid]
Buffer solution has two components. Upon dilution, the concentration of both are decreased to the same extent. Hence pH is constant upon dilution as the ratio of concentrations is constant.
Hope it helps!
