20. Write equations to show the presence of all ions in the aqueous solutions of
i. CH3COOH
ii. H3PO4
iii. HI
​

Answer 1

Answer:

Given below is the answer to this question

Answer 2

Equations are written below -

Aqueous solution refers to solution of water. Below are the equations for all given compounds -

i. CH3COOH

Known as acetic acid or vinegar. In aqueous solution it will ionise into -

CH3COOH + H2O --> CH3COO- + H3O+

ii. H3PO4

Also known as phosphoric acid. In aqueous solution it will ionise into -

H3PO4 + H2O --> H2PO4- + H3O+

It will further ionise as follows -

H2PO4- + H2O --> HPO4(2-) + H3O+

Further ionisation will take place as follows -

HPO4- + H2O --> PO4(3-) + H3O+

iii. HI

Also known as hydrogen iodide, it's ionisation reaction is -

HI + H2O --> H3O+ + I-
