Answer #1

KCN ( salt of HCN & KOH )

Strong base and weak acid so basic effect will dominate and pH will be greater than 7.0

CH3NH3I ( salt of CH3NH2 & HI )

Strong acid and weak base so acidic effect will dominate and pH will be less than 7.0 )

Al(NO3)3 ( salt of Al(OH)3 & HNO3 )

Strong acid and weak base. Acidic effect will dominate and pH will greater than 7.0
