Some effervescent tablets (like Alka-Seltzer) contain aspirin that dissolves when plopped into a glass of water. If a tablet contains 325 mg of aspirin and is dissolved in water to make 100 mL solution, what is the hydronium (H ) ion concentration?

The concentration of hydronium ion in the solution is 0.00225 M

Explanation:

To calculate the molarity of solution, we use the equation:

Given mass of aspirin = 325 mg = 0.325 g    (Conversion factor: 1 g = 1000 mg)

Molar mass of aspirin = 180.16 g/mol

Volume of solution = 100 mL

Putting values in above equation, we get:

The chemical equation for the reaction of aspirin with water follows:

Initial:                    0.0180

At eqllm:             0.0180-x                       x             x

The expression of for above equation follows:

We know that:

Putting values in above expression, we get:

Neglecting the negative value of 'x' because concentration cannot be negative.

Hence, the concentration of hydronium ion in the solution is 0.00225 M

d: the voltage of the secondary coil is less than that of the primary coil.
