1
Q

two common laboratory acids

A

sulfuric acid and hydrochloric acid

2
Q

what is a strong acid

A

acids that break up (dissociate) almost completely when dissolved in water

3
Q

common laboratory bases

A

sodium hydroxide (caustic soda-drain cleaner) , calcium hydroxide

4
Q

neutralisation

A

the reaction between equal parts acid and equal parts base = neutral (salt and water)

5
Q

an example of a neutralisation reaction (chemical equation)

A

hydrochloric acid + sodium hydroxide = sodium chloride + water
HCl + NaOH = NaCl + H2O

6
Q

Titration

A

The method of adding one solution from a burette to another solution in order to find out how much of the two solutions will just react with each other

7
Q

titrate HCl against NaOH

A

Acid Above (burette) Base Below (pipette) use methyl orange as indicator, add acid until one drop turn it pink

8
Q

what is in acid rain , where do they come from

A

sulfur dioxide from burning fossil fuels and nitrogen oxide from car emissions

9
Q

acid rain damages ..

A

trees, fish and limestone, and washes away calcium from soil

10
Q

solving problem of acid rain

A

limestone (base) is used to remove sulfur dioxide from power stations emissions

  • catalytic converters in cars remove harmful oxides of nitrogen in exhaust fumes
  • more renewable energy, less fossil fuels
