Question

Acids give h+ions in water true or false

Answer 1

━━━━━━━Ａｎｓｗｅｒ━━━━━━━━

No, acids do not give h+ ions in water. Acids give H3O+ ions or hydronium ions with mixing with water.

Ꭺcids are defined as the compounds which contains one or more hydrogen atoms when dissolved in water, and produces hydronium ions(H3O+) the only positively charged ion.

Depending on basicity, acids are defined as the number of hydronium ions that can be produced by the ionization of one molecule of that acid in aqueous solutions.

• ᴍᴏɴᴏʙᴀsɪᴄ ᴀᴄɪᴅ : acid which on ionization in water produces one hydronium ion per molecule of the acid.

For example : Hydrochloric acid

HCl + H2O → H3O+ +Cl-

• ᴅɪʙᴀsɪᴄ ᴀᴄɪᴅ : acids which on ionization in water produces two hydronium ions per molecule of the acid.

• ᴅɪʙᴀsɪᴄ ᴀᴄɪᴅ : acids which on ionization in water produces two hydronium ions per molecule of the acid. For example : Sulphuric acid

H2SO4 + H2O → H3O+ + HSO4-

HSO4- + H20 → H3O+ + SO4-

• ᴛʀɪʙᴀsɪᴄ ᴀᴄɪᴅ : acids which ionization in water produces three hydronium ions per molecule of the acid.

For example : Phosphoric acid

H3PO4 + H2O → H3O+ + H2PO4-

H2PO4- + H2O → H3O+ + HPO4-

HPO4- + H2O. → H3O+ + PO4-

So, hence we can say that, acids don't produce only h+ ions when mixed with water. It produces hydronium ions or H3O+ ions, in three different ways.
