PRESENCE OF SALT (SODIUM CHLORIDE) TEST: (WATER TEST 2)

Today during period 1 I tested for salt using my water samples (2).

(instructions + equipment same as test 1)

results shown below;
beaker 1: 4 drops = meduim
beaker 2: 2 drops = high
beaker 3: 3 drops = meduim
beaker 4: 3 drops = meduim
beaker 5: 2 drops = high

= the majority of salt taken from these samples are mainly meduim/high
