ACID AND BASES
DEFINATIONS -----------------------
Acid - A liquid substance that can dissolve metal and may burn our skin and clothes. Acid have a pH value of less than 7.
Base - Bases are substances that, in aqueous solution, release hydroxide ions , they are slippery to the touch , they taste bitter if an alkali, they change the colour of indicators , reacts with acids to form salt , promote certain chemical reaction such as base catalysis .
PHYSICAL PROPERTIES--------------------------
ACID - 1. They are sour in taste.
2.They react with carbonades and hydrogen carbonades to form salt, water, carbon dioxide gas.
3. Turn blue litmus red.
4. Acids corrode metals.
5. pH is less than 7.
6. Good electrolytes.
7. Phenolpthelien turns clourless.
