1a. Salts can be made by an solution by adding an alkaline solution (or the other way round!).

1b. A known volume of acid is measured out with a measuring cylinder or more with a and suction bulb and indicator is added and turns .

2. The is added with a measuring cylinder, or more accurately with a .

3. The alkali is added until the turns . The required for is noted. If too much alkali is added the indicator turns !

4. The procedure can now be without the contaminating indicator. The solution is then to reduce the amount of water.

5. The hot solution can be left to cool and .

6. This method uses soluble alkaline metal hydroxides which react with acids to form a salt and water. Complete the following:
(a) hydroxide + nitric acid ==> potassium + water
(b) sodium hydroxide + acid ==> chloride +
(c) lithium hydroxide + sulphuric acid ==> + water
