The pH is measure from 1 to 14. so, from 1 to 6.9 the substance is acidic. and from 7.01 to 14 the substance is basic. 7 is neutral. The closer the substance is to 7 it is either basic or acidic. As the number is lower the substance is more acidic for example: pH 2.9 is more acidic than pH 4.8
If a substance is added to water and the pH decreases is that substance an acid or a base?
pH of 1 to < 7 indicates an acid pH of >7 to 14 indicates a base pH of 7 indicates water

What is the pH of a substance?
The pH is the negative log of the concentration of hydronium ions. (pH=-log [H3O+]) If the pH is high, the substance is basic. If it is low the substance is acidic. When the pH is exactly 7 the substance is neutral.
Which is the most acidic pH 2 pH 5 pH 7 or pH 11?

If a substance has a pH of 1 is it a strong or weak acid?
Strong because a substance with a pH of 7 is considered neutral, so the further away from 7 the pH gets, the more strong of an acid it becomes.
