each number on the pH scale is apower of 10.

so 6 minus 4 = 2, 10 to the two is?

you got it

One hundred times. pH is a logarithmic scale, so each pH unit represent a 10-fold increase (or decrease) in concentration.

pH = log 1/[H+]

for pH 4 1/[H+]=10^4 and [H+] =10^-4

for pH 6 1/[H+]=10^6 and [H+] =10^-6

10^-6/10^*4 =10^2 =100
