Answer:

Electrolytes are substances that can ionize in water. They could be acids, bases or salts as long as they give ions when they dissolve in water.

Explanation:

Strong electrolytes completely ionize when dissolved in water, leaving no neutral molecules. The strong electrolytes here are: salt water, baking soda (NaHCO3) solution.
Weak electrolytes do not completely dissociate in solution, and hence have a low ionic yield. Examples of this would be vinegar and bleach (which could be sodium hypochlorite or chlorine, which are weakly dissociated).
Non-electrolytes will remain as molecules and are not ionized in water at all. In this case, sugar solution is a non-electrolytes, even though sugar dissolves in water, but it remains as a whole molecule and not ions.

Answer:

SAr = 3.75 E-3 M ≅ 4.0 E-3 M

Explanation:

Henry's law:

∴ Sg: gas solubility (mol/L)

∴ Kh: Henry's constant ⇒ Kh Ar = 1.5 E-3 mol/atm.L.....from literature

∴ Pg: Partial pressure of gas on solution (atm)

If Pg = 2.5 atm

⇒ Sg = (1.5 E-3 mol/atm.L)(2.5 atm)

⇒ Sg = 3.75 E-3 M
