Water Testing Kit

Preparation

• Take 25ml of water sample in the test bottle (No-1 )
• Add 4 - 5 drops of Total Alkalinity Reagent-2 (TA - 2) and mix until an orange yellow colour develops.
• Add Total Alkalinity Reagent-l (TA - 1), shake well after each drop until the colour changes from orange yellow to orange red.
• Count the no. of drops of TA - 1 required for colour change.
  Total Alkalinity: no. of drops x 5
  (p.p.m. in terms of CaCO3)
  pH (0-10)
• Take 10ml of water sample in the test bottle (No-1)
• Add 3 - 4 drops pH-Reagent-1 (pH - 1) and mix well. The colour that forms is compared with the pH colour chart.

Preparation

• Take 25 ml of water sample in the test bottle (No- 1)
• Add 10 drops of Total Hardness reagent-2(TH-2) and mix.
• Add few specs of Total Hardness reagent- 1 (TH- 1) and mix until a distinct pink colour develops.
• For Hard water, add Total Hardness reagent-3 (TH-3), shake well after each drop until the colour changes from pink to blue.
  Count the no. of drops of TH-3 required for colour change.
  Total Hardness = no. of drops x5
  (p.p.m. in terms of CaCO3)
• For soft water, add Total Hardness reagent-4 (TH-4), shake well after each drop until the colour changes from pink to blue.
• Count the no. of drops of TH-4 required for colour change.
  Total Hardness = no. of drops x 2
  (p.p.m. in terms of CaCO3)

Preparation

(For the detection of Acidity and Heat Stability of Milk)

Testing Method

• Place 2 drops of milk on the glass plate and add 2 drops of Alizarin Red - 5 Solution.
• Mix the contents with the glass rod throughly.
• Note the colour of the mixture and presence of any flakes or clots.
• The presence of a flake or clot indicates a positive test.
• Milk showing positive test is not suitable and not considered for the manufacture of evaporated milk.
