Basic, Acidic, and Neutral Salt Solutions

Question 1

basic, acidic, and neutral salt solutions

Answer 1

• salt solutions can be acidic, basic, or neutral depending on their interaction with the water in which they are dissolved
• NaOH + HF -> NaF + H2O (salt of strong base and weak acid)
• NaF -> Na+ + F-
• F- + HOH -> HF + OH- ([OH-] increases, basic solution)
• NH3 + HBr -> NH4Br (salt of weak base and strong acid)
• NH4Br -> NH4+ + Br-
• NH4+ +H2O -> NH3 + H3O+ ([H3O+] increases, acidic solution)
• NaOH + HCl -> NaCL + H2O (salt of strong base and strong acid)
• Na+ + H2O -> No reaction
• Cl- + H2O -> no reaction (no increases, neutral solution)
