Question

what is the hydronium ion molarity if the ph of a solution is 6.62? use 3 significant figures in answer and write answer in scientific notation i.e., 1.43e-4 or 1.43e-4. no spaces in answer!

Answer 1

The hydronium ion molarity if the ph of a solution is 6.62 will be 3.02 × 10⁻⁷ M

pH of solution = 6.62

Hydronium ion molarity = ?

The formulae for pH is:

   pH = -log [H⁺]

we will find out the hydronium ion molarity by using the above equation

  6.62 = -log [H⁺]

We have to find out the hydronium ion molarity; so change the place of the log to another side of the equation.

As we know that when we change the place of log to other side of the equal to sign we change log to antilog

   H⁺ = antilog (-6.52)

   H⁺ = 3.02 × 10⁻⁷ M

the hydronium ion molarity if the ph of a solution is 6.62 will be 3.02 × 10⁻⁷ M
