Question

When an acid dissolves in water, what ion does water form?

Answer 1

Answer:

Well, we conceive it to be the  

hydronium ion.......

Explanation:

Water is conceived to undergo an autoprotolysis reaction

under standard conditions.

When an acid, say  

H X

, is dissolved in water, we conceive it to INCREASE the concentration of the characteristic cation,  

H 3 O +

, and accordingly reduce concentrations of the characteristic anion,  

H O −

, so that the autoprotolysis equilibrium is maintained.

And a base likewise increases concentrations of the characteristic anion,  

H O −

.

We can quantify the acid-base equilibrium in water under standard conditions
