Does having a lower pH cause more acid?

Question

im not so smart with this stuff, but what causes the acid? like a lower ph, or a higher ph?

Answer 1

Actually, a substance being more acidic results in a lower pH, not the other way around.

pH is just short for "concentration of H+ ions".

Answer 2

lower pH means more acidic compared to higher pH.

pH = -log [H+]

more [H+] more stonger is the acid

Say pH=1 and pH=4

in case of pH =1, [H+] = 0.1 and for pH =4, it would be 0.0001

Answer 3

lower ph is acidic and higher ph is alcaline
