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?
a
Decrease the water temperature, which increases the solubility of the bath bomb - dissolving it more quickly.
b
Increase 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 acidity to a pH of 2, which increases neutralization of the bath bomb - and then take a shower, instead
b
Increase the water temperature, which increases the solubility of the bath bomb - dissolving it more quickly.
b
Increase the water temperature, which increases the solubility of the bath bomb - dissolving it more quickly.
To get the answer to this question, we need to understand the factors that affect the dissolution of a bath bomb. A bath bomb is made of a weak base and a weak acid, which react with each other when in contact with water.
One factor that affects the dissolution of a substance is temperature. Generally, an increase in temperature increases the solubility of solid substances. Therefore, increasing the water temperature would increase the solubility of the bath bomb, helping it dissolve more quickly.
So, option b, "Increase the water temperature, which increases the solubility of the bath bomb - dissolving it more quickly" would be the correct answer.
Option a, "Decrease the water temperature, which increases the solubility of the bath bomb - dissolving it more quickly," is incorrect because decreasing the water temperature decreases the solubility, making the bath bomb dissolve slower.
Option c, "Decrease the water volume, which increases the solubility of the bath bomb - dissolving it more quickly," is also incorrect. The volume of water does not affect the solubility of the bath bomb.
Option d, "Increase the water acidity to a pH of 2, which increases neutralization of the bath bomb - and then take a shower, instead," is unrelated to the dissolution of the bath bomb.
In summary, the correct answer is option b: Increase the water temperature to increase the solubility of the bath bomb, dissolving it more quickly.
