Exercise \(\PageIndex{1}\)
Which of the following would conduct electricity well if dissolved in water?
A) glucose (C6H12O6)
B) baking soda (NaHCO3)
C) ethanol (C2H6O)
- Answer
-
B) baking soda (sodium bicarbonate) is ionic and dissociates into ions when dissolved.
Exercise \(\PageIndex{1}\)
Which of the following would result in increased solubility of a gas in water?
A) increased pressure
B) increased temperature
- Answer
-
A) increased pressure, according to Henry's Law, increases the solubility of a gas. Increased temperature generally decreases the solubility of a gas in water.
