Orange juice has a ph of 4. what is its relative acidity compared to pure water, which has a ph of 7? orange juice has a ph of 4. what is its relative acidity compared to pure water, which has a ph of 7? 10 times more acidic 100 times more acidic 1,000 times more acidic 10,000 times more acidic

- Third option is correct, relative strength of orange juice to pure water is 1000 times

Solution:- pH is a way to represents the strength of the acids. Lower is the pH higher is the acid strength and higher is the pH lower is the acid strength. So, we could say that acid strength is inversely proportional to the pH.

From given pH value, we calculate the hydrogen ion concentration and then compare the hydrogen ion concentrations of the two acids to find out the relative strength.

for orange juice = and for pure water it is .

So, the relative acidity of orange juice compared to pure water =

= 1000

So, third option is correct, the relative strength of orange juice to pure water is 1000 times.
