Concept explainers
(a)
Interpretation:
Whether hydrogen chloride is a strong, weak or non-electrolyte is to be determined.
Concept introduction:
The electrolyte is the substance that produces ions when it is dissolved in a polar solvent. It breaks into positively and negatively charged ions that spread uniformly through the solvent. The electrolytic solution, as a whole, is electrically neutral. Sodium chloride, potassium chloride, calcium phosphate are some of the examples of electrolytes.
Strong electrolytes are those electrolytes that completely dissociates into its ions. These have a very high value of electrical conductance. Sodium chloride and potassium chloride are strong electrolytes.
Weak electrolytes are those electrolytes that partially dissociates into its ions. They are poor conductors of electricity. Acetic acid and carbonic acid are weak electrolytes.
Non-electrolytes are the substances that don’t dissociate into ions when they are dissolved in any solvent. They don’t conduct electricity. Urea, benzene, chloroform are non-electrolytes.

You should also record any numeric observations (masses, volumes, concentrations).Make sure they are organized and labeled so it is clear what the observation of electrochemistry redox reaction (Oxidation Reduction)experiment. Here is the data for the electrochemistry redox reaction (Oxidation Reduction)experiment: The first part was testing the observed vs theoretical cell potentials for the following voltaic cells: Zn/Cu reading was 0.914 Zn/Al reading was 0.210 Zn/Ag reading was 1.330 Al/Cu reading was 0.672 Ag/Cu reading was 0.413 Ag/Al reading was 1.000 The second part of the experiment was constructed an electrolytic cell using 2.008 grams of KI in about 100mL of DI water. Then measured the pH of the reaction mixture which was 5.22 with soultion in plain water and 10.74 with soultion added.arrow_forwardNaCN 15.
