Question

For each salt complete a Bronsted-Lowry acid-base reaction with water, indicating all conjugate acid-base pairs. Then use the reaction to explain if the salt solution is acidic, basic, or neutral in each case. 1. NH_4^+ Cl^- + H_2) rightarrow 2. NaCl + H_2O rightarrow 3. NaC_2H_3O_2 + H_2O rightarrow 4. K_2PO_4 + 3H_2O rightarrow 5. (NH_4)_2SO_4 + 2H_2O rightarrow

Answer 1

1.NH,"cl. + H2O HCl NH,OH conj.base - + conj.acid NH OH is weak baseand HClis strong acid. Hence, the solution is acidic 2.NaC + H2O>NaOHHCl conj.base conj acid d ena tHog d n sl 23 NaOH HC2H,O2 conj.base conj.acid 3.NaC.H,02 + H2O NaOH is strong base and HC2H O2 is weak acid. Hence, the solution i s baisic conj.base conj.acid KOH is strong base and H,PO4 is weak acid. Hence, the solution is baisic conj.base conj.acid NH,OH is weak baseand H,SO4 isstrong acid. Hence, the solution isacidic
