1.garam yg kelarutanny dlm air basa adlh ? CH3COOK, Na2SO4, NaCl, CH3COONH4, atau NH4Cl. 2. jika ka(CH3COOH)=1×10 pngkt -5 maka pH larutan CH3COONa 0, 1 M ad ? 3.jika 250ml CH3COOH 0, 1M(ka=1×10 pngkt -5) dicampurkn dgn 250ml larutan KOH 0, 1 M , pH campuranny ad ? thanks before

A. CH3COOK ( CH3COOH->asam lemah, KOH->basa kuat b. pH=9
b. pH=9
3.pH = 9
