Compound Chem Lab Report Question?

Question

I did a chem lab project to determine the solubility and conductivity of six compounds, and I know I've messed some results up but I can't figure which ones. If you could go through these and tell me which ones are wrong, I would really appreciate it.

paraffin - soluble r.t. water: no soluble hot water: no soluble in r.t. mineral spirits - no soluble in hot mineral spirits - yes conducts - no

dichlorobenzene - r.t. water, hot water, r.t. mineral spirits - no hot mineral spirits - yes conducts - yes

hydroquinine - r.t. water - no hot water, r.t. spirits - yes hot spirits - no conducts - no

sugar - r.t. water - no hot water - yes r.t. spirits, hot spirits - no conducts - yes

sodium nitrate - r.t. water, hot water - yes r.t. spirits, hot spirits - no conducts - yes

potassium chloride - r.t. water - no hot water - yes r.t. spirits, hot spirits - no conducts - yes

Thank you!

Answer 1

The general rule is "Like dissolves like." That means polar or ionic things in polar solvents (like water) and non-polar things (like paraffin) in non-polar solvents (like mineral spirits).

Ionic conducts, non-ionic dies not.

Paraffin above looks okay.
Dichlorobenzene is not ionic. I do not think it conducts.
Hydroquinone should be soluble in hot and cold mineral spirits.
Sugar is non-ionic. It should not conduct. Have you never put sugar into ice tea?
Sodium nitrate looks good.
Potassium chloride is similar to table salt (Sodium chloride). It should dissolve in cold as well as hot water.

Answer 2

A good lab report should contain the following sections: Title, purpose, experimental, results/data, and conclusions.
