Alab has 60 ml of a solution of uranium sulfate dissolved in water. based on the work done by the curies, how can the amount of radioactivity be reduced?

by adding more water to dilute the solution
by removing sulfate ions
by adding heat to raise the temperature
by removing uranium ions

Option (d) is the correct answer.

Explanation:

Curie studied the radioactivity of various radioactive elements. He also studied about uranium which is a highly radioactive element.

Therefore, when 60 mL of a solution of uranium sulfate dissolved in water then radioactive reaction that will be highly exothermic in nature.

This reaction only be reduced by removing the amount of uranium ions.
