Answer:
The concentration of h+ in stomach acid is times more than that of lemon juice.
Explanation:
Basically, pH is a value that rates how acidic or alkaline a solution is on a scale from 0–14. A pH of 7 is considered neutral. Any pH value below 7 is considered acidic and any pH value over 7 is considered alkaline. Acidic solutions have a lower pH, while basic solutions have a higher pH.
On the pH scale, the difference between adjacent numbers represents a tenfold difference in acidity. For instance, a pH of 4 is 10 times more acidic than a pH of 5 and 100 times more acidic than a pH of 6.
Since the lemon juice has a pH of about 2.0 compared to stomach acid with a pH of about 1.0 It means that the the stomach acid is 10 times more acidic than the lemon juice.
pH = -log10[H+]
[H+] = 10^-pH
In Lemon juice;
[H+] = 10^-pH = 10^-2 = 0.01
In stomach acid;
[H+] = 10^-pH = 10^-1 = 0.1
0.1 is 10 times more than 0.01.
