Answer:
10x higher
Explanation:
To convert pH to [H+], you would use the formula:
[H+] = [tex]10^{-pH}[/tex]
pH of 3.0:
[H+] = [tex]10^{-3.0}[/tex]
[H+] = 1 x [tex]10^{-3}[/tex]
pH of 4.0:
[H+] = [tex]10^{-4.0}[/tex]
[H+] = 1 x [tex]10^{-4}[/tex]
Divide to find how many times larger.
[tex]\frac{1 x 10^{-3} }{1 x 10^{-4} } = 10[/tex]
