Will 0.10 M aqueous solutions of the following salts be acidic , basic or neutral? (Assume a solution is neutral if its pH is 7.00±0.05). Equilibrium constants may be found in an appendix to your text. acidic basic neutral: sodium sulfate (Na2SO4) acidic basic neutral: sodium hydrogen arsenate (Na2HAsO4) acidic basic neutral: ammonium sulfite ((NH4)2SO3) acidic basic neutral: sodium chloride (NaCl) acidic basic neutral: ammonium chloride (NH4Cl)

questions are in red
Consider the following salt solutions: (i) NH4Cl – NH+ + C- Notice that as a salt, NH,Cl dissociates completely in solution. So, what are the parents of this salt? The cation, NH, in this case, is from the base obtained by adding enough OHto balance the positive charge(s) on the cation; Viz, NH,OH. Similarly, the anion, Cl. comes from the acid. So the parent acid can be obtained by adding enough Hi to neutralize the charge...
