The difference between a pH of 5 and a pH of 8 is
Kaylis [27]

Answer:

The correct answer is - D) 1000x.

Explanation:

pH is a logarithmic scale, 1 reading change leads to the results in ten-fold in the   H+ concentration in acidity/basicity. The more  H +  ions found in solution, the more acidic the substance is as acids donate  H +  ions.  

You can calculate the concentration of  H +  from the pH and the equation  

p H  = − log [ H + ]

arrange again

[ H + ]  =  10 − p H

So for a pH of 8, we get  [ H + ]  = 10 ^− 8

For a pH of 5, we get  [ H + ] = 10^ − 5

 10 ^−5  /10 ^− 8= 10 ^3

=  1000
