Would you like a nice, refreshing glass of acid?

This is just what you get when you have a glass of lemonade.

Compounds which contain the element hydrogen (H) and change blue litmus paper to red. Litmus paper is called an indicator by scientists because it indicates or tells a scientist whether a substance is an acid or a base. Acids in food have a sour taste.

Hydrochloric Acid HCl Treating metal before painting: swimming pools Sulfuric acid H 2 SO 4 Fertilizers Nitric acid HNO 3 Explosives Acetic acid CH 3 COOH Acid in vinegar Citric acid H3C6H5O7H3C6H5O7 Manufacturing flavorings and soft drinks and acid in fruit

Contain the elements oxygen and hydrogen together called hydroxide (OH) Turn red litmus paper blue Bitter (soaps and detergent) NEVER TASTE A SUBSTANCE TO IDENTIFY IT AS A BASE. Slippery feeling when touched

Sodium hydroxide NaOHSoap Cleaning drains Calcium Hydroxide Ca(OH) 2 Treating polluted lakes & making cement AmmoniaNH 3 Cleaning solutions

1. HNO 3 2. NaOH 3. HCl 4. KOH 5. H 2 SO 4 6. HBr 7. Ca(OH) 2

Range of values from 0 to 14 Expresses the concentration of hydrogen ions in a solution Low pH tells you that the concentration of hydrogen ions is high High pH tells you that the concentration of hydrogen ions is low
