Which of the following solutions contains the largest number of moles of dissolved particles? a.) 25 ml of sodium chloride b.) 2

kirza4 [7]

Answer:

b.) 25 ml of aluminum hydroxide

Explanation:

For this question, we have to assume that we have the same concentration for all the solutions, for example, 1 M. Additionally, we have to take into account the ionization reaction for each species:

a) $NaCl~->~Na^+~+~Cl^-$ we have to ions

b) $Al(OH)_3~->~Al^+^3~+~3OH^-$ we have fourth ions

c) $CH_3COOH~->~CH_3COO^-~+~H^+$ we have two ions

d) $C_6H_1_2O_6~->~C_6H_1_2O_6$ we have one ion

If we have the same volume and the same concentration the variables that will help us to answer the question would be the number of ions. If we have more ions we will have more particles dissolved. Therefore the answer would be b) (due to the fourth ions).

I hope it helps

Calculus, originally called infinitesimal calculus or "the calculus of infinitesimals", is the mathematical study of continuous change, in the same way that geometry is the study of shape and algebra is the study of generalizations of arithmetic operations.
