Human blood has an approximate ph of 7.3. which substance is more basic than human blood?

 A water and ammonia solution with a pH of 11

Explanation:

It is known that when pH of a substance or solution is equal to 7 then it is called a neutral solution. A pH less than 7 is called an acidic solution and a pH greater than 7 is known as a basic solution.

Since, pH of human blood is 7.3 this means that it is slightly basic in nature. On the other hand, a solution that will have pH more than 7.3 will be more basic than human blood.

For example, pH of ammonia solution is 11.6. Therefore, it is very basic in nature.

Also, it means that solution is more basic than human blood.
