(10) Thermometers
(11) The gas stove
(12) Pipette volume of 10 ml
(13) and the stand Buret
(14) The test tube rack + spray bottle
material
(1) distilled
(2) KMnO4
(3) red litmus paper
(4) Oxalic acid (H2C2O4)
(5) Buffer solution having a pH 4 and pH 7.
Ways of working
(1) The degree of acidity (pH)
(A) Take a water sample to be measured pH and input into the beaker.
(B) Calibration of the pH meter with buffer solution pH 4 and pH 7.
(C) Dip the pH meter into the water sample. The numbers on the right come into one’s vision pH meter pH value of the water sample.
(2) Temperature / Temperature
(A) Prepare the sample (unscrew the sample bottle)
(B) Dip the temperature gauge (thermometer or O2 meter) into the sample, make sure your hands are not in contact with the gauges.
(C) Read the numbers listed on the tool.
(3) The solid dissolved and suspended solids
(A) Take a sample of 100 ml with a measuring cup and pour it into a beaker and heat.
(B) Consider whether the sample becomes turbid or no buildup! If the sample became turbid means no dissolved solids, whereas in case of significant sediment samples contained suspended solids.
(4) Color
(A) Take the sample into a test tube as much as ± 3/4 of the volume of the reaction tube.
(B) Compare the color with a standard solution that has been provided.
(5) Ammonia (NH3)
(A) Enter 10-15 ml of sample into a test tube.
(B) lipatkan red litmus paper into a test tube. Heat up spritus
(C) Observe the sample, whether the smell rancid or not. If the sample contains ammonia smell rancid or red litmus turn blue.
