THE COMPLETE QUESTION IS:

Determine whether each cation is acidic or pH-neutral. For those cations that are acidic, write an equation that shows how the cation acts as an acid . a. NH+4 b. Na+ c. Co3+ d. CH2NH+3

a. Acidic

b. neutral

c. Acidic

d. Acidic

Explanation:

a. NH4+ + H2O <==> NH3 + H3O+ (NH4+ is a conjugate acid of a weak base. Therefore it is acidic)

b. Neutral. Na+ is a cation of a strong base. Therefore it's pH is neutral.

c. Co(H2O)6³+ + H2O <==>CoH2O5(OH)²+ + H3O+

(Therefore Co+ is a weak acid since hydronium ion is formed.)

d. CH2NH3+ is a conjugate acid of a weak base. Therefore it is acidic.
