We planned to have water quality checking kit. However, some issues have occurred so we couldn't experiment our water sample with the kit. Fortunately, we have Plan B, which include: checking turbidity, checking pH rate, and microscope checking. So we could conclude our experiment successfully. <<NOTICE>> Water sample 1-Giang Vo lake Water sample 2-Ngoc Khanh lake Water sample-To Lich river Lake FIRST STEP -CHECKING TURBIDITY Beaker 1 and 2 seem very clean. Just like purified water. But Beaker 3 was totally black and smelled like a rotten egg. SECOND STEP -CHECKING pH RATE Despite our expectations, these water samples were very alkalic. Among them, sample 3 was the highes...

After the cleaning, they put lake water ba...
