PRESENCE OF PHOSPHATE TEST: (WATER TEST 2)

Today during class (period 1) I tested for phosphate in my water samples (Sample 2).

(instructions + equipment same as test 1)

results shown below;
beaker 1: 0 = meduim pale yellow colour
beaker 2: 0 = meduim pale yellow colour
beaker 3: 0 = meduim pale yellow colour
beaker 4: 0 = meduim pale yellow colour
beaker 5: 0 = meduim pale colour

= as you can see there is no reading of phosphate present in the water being sampled
