I need help with chem???? :(?

Question

Can someone help me.

1. dilute sulfuric acid is added to a solution of barium acetate.

2. Ammonium chloride crystatls are added to a solution of sodium hydroxide.

PLease explain how to write these.........

Answer 1

These are both acid base reactions.

1. H2SO4(aq) + Ba(CH3COO)2(aq) --> BaSO4(aq) + 2CH3COOH(aq)

    strong acid + weak base --> weak acid

2. NH4Cl(aq) + NaOH(aq) --> NH3(aq) + NaCl(aq) + H2O(l)

    weak acid + strong base --> weak base

Just remember this:

strong acid + weak base --> weak acid

weak acid + strong base --> weak base

weak acid + weak base --> salt + water (neutral solution)

strong acid + strong base --> salt + water (neutral solution)

Answer 2

Are you just writing the equations?

1. H2SO4 + Ba(CH3COO)2 --> BaSO4 + 2CH3COOH

Barium sulfate will precipitate, and acetic acid will just be in solution

2. NH4Cl + NaOH ---> Na+ + Cl- + NH4+ + OH-

none of the products above will crystallize, so they will just float around in solution
