3 ph

Answer:

pH is a logarithmic scale. A solution with a pH of 2 has an H+ concentration 1000 times higher than a solution with a pH of 5. Officially pH is the negative logarithm of the molar concentration of the H+ ion in the solution.

Each number is a tenfold increase, so a solution having a pH of 2 is 10,000 times (or 10^4) more acidic than a solution having a pH of 6.

A pH of 6 is 1,000 times more acidic than a pH of 9. Each pH step is ten times than the next lower whole value. Since there are 3 steps between 6 and 9, 10 x 10 x 10 = 1,000.

100 times more acidic since pH number represents concentration of H+ atoms for exaple pH 1 = .1 concentration pH 2= .01 concentration pH 3= .o01 concentration etc.

Because the pH scale is a log base 10 scale the difference between 2 and 4 is 100x.

. Since the pH scale is determined by log it is 10 to the power of 3 more acidic so it's 1000 times more acidic

What is 20 more than 20?

"20 more than 20" means that you are adding 20 by 20. Then: 20 + 20 = 40 So 40 is 20 more than 20 because 40 - 20 = 20!
