Justin and Alejandro are conducting a chemical experiment involving sodium hydroxide. A key part of the reaction is ensuring that the sodium hydroxide is dissolved in water before adding the other materials. Justin adds the sodium hydroxide to reaction A, and begins stirring the mixture with a spoon. Alejandro also adds sodium hydroxide to his reaction, reaction B, but doesn't stir it because he is lazy. Whose sodium hydroxide, Justin's or Alejandro's, will dissolve faster?
Ans: Justin's
