GROUPS IV AND V REACTIONS 1) NH+ + NaOH = (turns moist red litmus paper blue) 2) NH3(aq) 3) Ca2+ + CO32- - 4) CaCO3 + HC H302 — 5) Ca2+ + C20,2 — 6) CaC2O4 + HCI — 7) Mg2+ + Na2HPO4 + NH3 —

Answer 1

1) NH₄⁺ + NaOH $\rightarrow$ Na⁺ + NH₃ + H₂O

2) NH₃$\rightarrow$ NH₄⁺ + OH^-

3) CaCO₃

4) CaCO₃ + 2 CH₃COOH $\rightarrow$ Ca(CH₃COO)₂ + H₂O + CO₂

5) CaC₂O₄

6) CaC₂O₄ + 2 HCl $\rightarrow$ CaCl₂ + H₂C₂O₄

7) MgNH₄PO₄ + 2 Na
