Whats the strongest base on the ph scale? A. HCI B. NaOH C. blood D. saliva

NaOH

Explanation:

The sodium hydroxide is strongest base because it fully dissociate into ions.

It dissociate to gives the sodium and hydroxyl ions and solution became more basic.

NaOH → Na⁺ (aq) + OH⁻ (aq)

Its pH is 12. It is also known as caustic soda.

Other given Options:

The pH of blood is vary from 7.35 - 7.45. it is slightly alkaline.

The pH of HCl is 3.

The pH of saliva is 6.2 - 7.6.

We know that neutral pH is 7 the pH less than 7 is acidic so HCl is acidic because its pH is 3.

The pH is greater then 7 is basic so saliva and blood are basic but less than the NaOH.
