, (b) Alkali metals react with water to produce an alkaline solution and hydrogen gas.
A test tube of gas can be tested to see if the gas is hydrogen by putting a lighted
splint at the top of the test tube.
A student suggests the following method to show that an alkaline solution and
hydrogen gas are produced in this reaction.
step 1 pour 150 cm3 water into the container shown in Figure 2
step 2 add a small piece of lithium to the water in the container shown in Figure 2
step 3 hold a lighted splint above the container
step 4 hold some damp red litmus paper above the mixture in the container
