Determine the molarity of a solution of the weak acid HCl)2; Ka = 1.10*10^-2 if it has a ph of 1.25?
This is a fact that Bromine(Br) is larger than chlorine(Cl) but indication of equilibrium constant suggests that a bromo substituent has a less preference for the equatorial position than chloro substituent? Explain it briefly?
