Which of the following are Arrhenius acids?

(a) H2O

(b) Ca(OH)2

(c) H3PO3

(d) HI

ANSWER:

Solution 5P

Here we have to explain which of the following are Arrhenius acids.

According to Arrhenius concept, a substance is said to be Arrhenius acid if it dissociate H+ ion when dissolved in water. Alternatively Arrhenius acid contains hydrogen and produces hydronium ion (H3O+) in aqueous solution.

Step 1

(a) H2O

H2O is an arrhenius acid because it produces H3O+ ion in aqueous solution. Water (H2O) can also be called as arrhenius base because it produces the OH- ion as well.

Thus H2O is an Arrhenius acid.
