Experimental วืธี TOP
I introduction experiment are
1.? This experiment requires the same mass and water have the volume rate all the time. To compare the dissolution of compounds in the water 2
.Should write the numbers or letters directed at the test tube all tubes to note that is any substance
.
1 experiment method. The following substances is LiCl Na2CO3 Na2HPO4 KNO3 Na2SO4 each type 0.5 g down in vitro medium type one tube. Then add distilled water into the tube, it 10 cm3 shake observation of melt. The solution to the next
2. Put MgCl2 CaCl2 SrCl2 BaCl2 and each 0.5 g into large 4 tube, test tube type and add distilled water into the tube, each 10 cm3 shake. Observe the situation melt solution stored to experiment 3 next
.Pour the solution MgCl2 from an 2 tube, a small experiment 5 tube, each 2 cm3 and concentration LiCl Na2CO3 and Na2HPO4 KNO3 Na2SO4. From the 1 each type 2 cm3 into each tube respectively
4.Experiment, as well as an 3 but use the solution CaCl2 SrCl2 BaCl2 solution and instead MgCl2
the experimental results TOP 1. LiCl Na2CO3. Na2HPO4 KNO3 Na2SO4 MgCl2 and CaCl2 SrCl2 BaCl2 dissolved all
2.? When the two kinds of mixed solution will work as follows:
solution LiCl Na2CO3 Na2HPO4 KNO3 Na2SO4
.MgCl2
CaCl2
SrCl2
BaCl2
the debate after the experiment TOP
the results showed as follows:
1.? Compound chloride carbonate hydrogen phosphate, nitrate and sulfate of lithium, sodium, potassium, and dissolves in water well
2.
