use the acidity model pH=-log10 [H+], where acidity (pH) is a measure of the hydrogeon ion concentration [H+] (measured in Miles of hydrogen per liter) of a solution.

Answer:

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
