Question

Got It? Chemistry The pH of a substance equals -log[H+], where (H+] is

the concentration of hydrogen ions. Suppose the hydrogen ion concentration for
Substance A is twice that for Substance B. Which substance has a greater pH level?
What is the greater pH level minus the lesser pH level? Explain.

Answer 1

The substance A has a greater pH.

pH is directly proportional to hydrogen ion concentration [H+], i.e the higher the [H+], the higher it pH.

Greater pH level - lesser pH level is 14.

why? it is so because, on the standard pH scale the highest point is 14 and the lowest point is 0.

Therefore the difference between those points is 14.
