consider how they were formed and the reverse equilibrium reaction:
Cu(OH)2 + 2HCl >> CuCl2 + 2H2O The reverse reaction will be strong acid, weak base, so litmus will be red
Cu(OH)2 + H2SO4>>CuSO4 + 2H2O... reverse reaction produces strong acid, weak base, litmus red.
NH4 (OH) + HCl >>NH4CL + H2O reverse, acid.
Cu(OH)2 + 2HCl >> CuCl2 + 2H2O The reverse reaction will be strong acid, weak base, so litmus will be red
Cu(OH)2 + H2SO4>>CuSO4 + 2H2O... reverse reaction produces strong acid, weak base, litmus red.
NH4 (OH) + HCl >>NH4CL + H2O reverse, acid.
