A solution has a pH of 2.5. what is the H+

The concentration of in the solution is

Explanation:

pH is defined as the negative logarithm of hydrogen ion concentration present in the solution.

     .....(1)

We are given:

pH of solution = 2.5

Putting values in equation 1, we get:

Hence, the concentration of in the solution is

the temperature of the gas, in k, not celsius.

answer:

technetium is the most reactive. this is followed by silver. the least reactive out of these three elements is strontium.
