How much more [H+] does lemon juice (pH 2) have compared with pure water (pH 7)? Remember that each pH unit represents a 10 fold
zhenek [66]

Answer:

10^5 \\or\\100,000

Explanation:

As we know that the formula for pH is

pH = -[log H+]\\

It is also given in the question that one pH unit represents the 10 fold change in the concentration of hydrogen ion.

Now for lemon juice whose pH is 2, hydrogen ion concentration is equal to

10^-2\\= \frac{1}{100}

And for pure water whose pH is 7, hydrogen ion concentration is equal to

10^ -7\\= \frac{1}{10000000}

Thus, the H+ ion concentration in lemon juice is 10^5 times greater than the pure water.
