Hydrogen-ion concentration test

This morning I received a call from the expedition team at 9:35. The weather was fine and the temperature was -35°C. Their current position was 83 degrees 05 minutes North and 71 degrees 32 minutes West.

The blizzard continued since yesterday and the outside was a whiteout. When I was about to go shopping at CO-OP, Lucas at the cafeteria told me "Take a GPS with you, or you will get lost."

When I went back to the hotel, I found the snow collected yesterday had already melted. So I measured the concentration of hydrogen ion.

1. Place this cup above 1m from the ground outside to collect the snow. 2. After the cup is filled with the snow, wrap it and keep it inside a room and wait until it melts. 3. When the snow has melted, measure the amount of the water.

4. Washing plastic bottles by distilled water

5. Keep the snow-melted water inside the plastic bottles and place them outside once again

6. Using a simple measurement kit "Simple Pack" test the rest of the water not put in the plastic bottles. This simple pack contains a color fixing agent and according to the acid level the water turns into 14 different colors.

The color above means pH6.0 which is normal.

pH5.6 or above indicates normal acid level pH4.1 - pH5.5 indicates high acid level (acid rain) pH4.0 or below indicates very high acid level
