Chemical property of bases and acids

Physical property of bases

taste bitter. feel slippery. dark chocolate. soap

Physical property of acid

taste sour. citrus fruits (lemons)

base PH

under 7

Chemical property of bases

- corrosive - release negatively charge hydroxide ions (OH) in water

Chemical property of acid

-corrosive (react with metals and skin.) rust -release positively charged hydrogen ions (H) in water

ph scale

-tells us whether substance is an acid or a base -ranges from 0-14 the number 7 is in the middle "neutral" neither a base or acid

PH

potential of hydrogen

water

acid and bases often react with each other to form water.

indicator

changes color find out if a substance is an acid or a base

neutralization

chemical reaction that reduces the properties of the acid and base

salt

compounds made of a metal and non metal that are formed when acids and bases react.

acid PH

over 7

examples of indicator
