2

4.       Stiring spoon

5.       Chemical Glass

Activity Step

1.       Prepare the Instrument and materials.

2.       Dissolve  all materials in the pure water

3.       Test all of materials with electrolyte tester

4.       Observe the symtoms happens in the solution and on the lamp

Question and assignment

1.       What are the symptoms observed from testing of each solution? Express in table.

2.       Group the substance which in the solution form electrolyte solution and nonelectrolyte

Result of Experiment

No	Solution	Reaction		Electrolyte intensity		Nonelectrolyte
		Lamp	Bubbles	Weak	Srong
1.	Marimas	Not	-			ya
2.	MSG (vetsin)	Dreary	ya	ya		-
3.	KCl	Bright	ya		ya	-
4.	Gula jawa	Not	-			ya
5.	Urea	Not	-			ya

Conclusion

Electrolyte solution shows bubble and bright lamps reaction, because it has good electricity. Meanwhile nonelectrolite solution don’t show reaction at all, because it has not electricity.
