5.0*10^5 M

Step-by-step explanation:

Since we have defined pH as the negative logarithm of hydrogen ion concentration. This implies that mathematically we can write;

pH = - log[H^+] of course, log here is the same as log10 (logarithm to base 10).

Hence I can rewrite the definition of pH above as the negative logarithm to base 10 of hydrogen (or oxonium) ion concentration.

Since

pH = - log[H^+]

It follows that;

[H^+] = Antilog (-pH)

Hence if the pH of the solution has been given as 4.3

[H^+] = Antilog (-4.3)

[H^+] = 5.0*10^5 M
