Question

Based on the behaviors of acids and bases, identify which procedures you would have used to examine an unknown acid that would also be applicable to examining an unknown base.

Check ALL THAT APPLY.
**determining the molar mass
**measuring the pH
**diluting the sample solutions to characterize as a weak or strong base
**isolating a sodium salt of the weak base
**determining the equilibrium constant

Answer 1

To examine an unknown acid and an unknown base, the following procedures can be used:

1. Measuring the pH: This procedure can be used to determine whether the substance is an acid or a base. Acids have a pH less than 7, while bases have a pH greater than 7.

2. Diluting the sample solutions to characterize as a weak or strong base: This procedure can be used to determine whether the substance is a weak or strong base. Weak bases do not completely dissociate in water, while strong bases do.

3. Determining the equilibrium constant: This procedure can be used to determine the strength of an acid or a base. The equilibrium constant is a measure of how much of the acid or base dissociates in water.

Therefore, the procedures that are applicable to examining both an unknown acid and an unknown base are measuring the pH, diluting the sample solutions to characterize as a weak or strong base, and determining the equilibrium constant.
