They have a pH from 8 to 14.
Both acids and bases.
very weak bases
Acids have a lower PH and bases have a higher PH.
The pH of bases is over 7.
Bases are anything above a 7 on the pH scale. A substance with a pH of 7 is considered neutral.
Glue usually possess a "base" ph level. Bases have a ph level of 7.
0 - 6 Acids7 Neutral8 - 14 Bases
Antacids are bases. Bases have a pH higher than 7...So, no.
pH is a measure of the acidity or basicity of a solution, with acids having a pH below 7 and bases having a pH above 7. Acids donate protons (H+) in a solution, while bases accept protons. Acids can neutralize bases and vice versa.
Bases have values higher than 7 Substances with a pH of 7 are neutral Acids have a pH below 7
Bases turn pH paper blue or purple in color.
Bases have pH's above 7 on the pH scale.
