A bath bomb is a solid sphere made of a weak base and a weak acid. When it you add it to a bathtub, it mixes with the water to create a soapy solution. If you want it to completely and quickly dissolve a large bath bomb, what might you do?

Question

Lush bath bomb: See how it's made from start to finish

a
Increase the water acidity to a pH of 2, which increases neutralization of the bath bomb - and then take a shower, instead
b
Decrease the water temperature, which increases the solubility of the bath bomb - dissolving it more quickly.
c
Decrease the water volume, which increases the solubility of the bath bomb - dissolving it more quickly.
d
Increase the water temperature, which increases the solubility of the bath bomb - dissolving it more quickly.

Answer 1

To quickly and completely dissolve a large bath bomb in water, the best option is:

d) Increase the water temperature, which increases the solubility of the bath bomb - dissolving it more quickly.

Increasing the temperature of the water generally increases the solubility of solids, allowing the bath bomb to dissolve faster.
