CH,COOH (acetic acid dissociates to make hydrogen ion and acetate ion) (bio H

Answer 1

a) Na_{​​​​​2}​​​​SO_​​4 ---> 2Na⁺ + SO_{​​​​​4}^{​​​​-2}

b) BaCl_​​​2​​ ----> Ba^​​​+2 + 2 Cl^{​​​​-}

C) (NH_{​​​​4})₂CO₃ ----> 2NH₄ ⁺ + CO_{​​​​​3}^{​​​​-2}

d) Ca(NO_​​3​)₂ ----> Ca⁺² + 2NO₃^-

e) HNO_{​​​​3}​​​ ----> H⁺ + NO_{​​​​​3}^​-

5) The reaction of dissociation of weak electrolytes are represented by using double arrow mark pointing opposite directions, as the weak electrolytes do not dissociate completely and usually develop equilibrium.

a) HF <------> H⁺ + F^{​​​​​​-}​​​

b) CH_{​​​​​3}COOH <-------> CH_{​​​​​3}​COO ^- + H⁺
