Expert Answer

pH less than seven

pH greater than seven

pH equal to seven

NH4I (Because cation NH4+ is not neutral cation)

NaNO2(Because anion NO2- is not neutral anion)

Ba(ClO4)2 (Anion and cation are neutral)

Cu(NO3)2 (Because cation Cu2+  is not neutral cation)

CaS (Because anion S2- is not neutral anion)

KBr (Anion and cation are neutral)
