Ответ:
an acid is any substance that has pH of less than 7. The pH scale is used to measure how acid or alkali a substance is:
Explanation:
0-3 = strong acid (UI turns red)
4-6 = weak acid (UI turns orange/yellow)
7 = neutral (UI turns green)
8-10 = weak alkali (UI turns blue)
11-14 = strong alkali (UI turns purple)
The pH of an acid is determined by the concentration of Hydrogen ions (H+) the substance has when in solution. All acids contain hydrogen ions when in solution; the higher the concentration of H+ ions, the lower the pH.
Fast Fact: Bee stings are acidic. They can be neutralized using baking powder which contains sodium hydrogen carbonate.
hope this helped.
