III.

Chemist glass Property to examine the electrolyte Distill water (H2O) Ethanol (C2H5OH) Sugar lateness (C6H12O6) Urea lateness (CO(NH2)2) Ammonia lateness (NH3) Hydro Chloride lateness (HCl) Vinegar lateness (CH3COOH) Potassium Chloride lateness (NaCl) Potassium Hydroxide lateness (NaOH) Ammonium Chloride lateness (NH4Cl)

PROCEDURE 1. Arranged the electrolyte examine’s property. 2. Prepare 10 clen chemist glasses, take each-lateness into the chemist glass until its half. 3. Examine the capacity of distill water to transmit the electric current with dip both electrode, observation it and record the result. After that, you can do the other observation. 4. Clean up the electrode with brushing water and use tissue to dry it before you use it to examine the other lateness capacity.

QUESTION:

1. Between all of the examined lateness, which ones are can transmit electric current? → Hydro Chloride Lateness, Potassium Chloride Lateness, Potassium Hydroxide Lateness, Ammonium Chloride Lateness.

2. Explain about electrolyte lateness! → Electrolyte lateness is a lateness that can transmit electrolyte current.

3. Why does the electrolyte lateness can transmit electrolyte current? → Because

4. Grouping all of the substance into strong electrolyte, weak- electrolyte or non electrolyte. → Strong electrolyte: Hydro Chloride Lateness, Potassium Chloride Lateness, Potassium Hydroxide Lateness, and Ammonium Chloride Lateness. → Weak electrolyte: Urea Lateness, Ammonia Lateness, and Vinegar Lateness. → Non electrolyte: Distill Water, Ethanol, and Sugar lateness

5. Between all of the examined lateness, which ones are have substance that includes: a) Ionic compound : NaCl, NaOH, b) Covalent compound :

6. Between all of the entire covalent compound in this experiment, which one are can produce ion-ion if put into water? →
