Which of the following solutions contains the largest number of moles of dissolved particles? a.) 25 ml of sodium chloride b.) 25 ml of aluminum hydroxide c.) 25 ml of acetic acid d.) 25 ml of nitric acid e.) 25 ml of sugar

b.) 25 ml of aluminum hydroxide.

Explanation:

Hello,

In this case, bu knowing the formula of each substance, we can predict the number of particles are going to be dissolved in the given solutions, thus we have:

Sodium chloride, NaCl: when it is placed in water, two ions, sodium and chloride are dissolved.

Aluminium hydroxide, Al(OH)3: when it is placed in water, four ions are dissolved, one aluminium (III) and three hydroxyl.

Acetic acid CH3COOH: when it is placed in water, and equilibrium dissolution is present, therefore, not all the acetic acid particles will be dissolved as ions, anyway, two ionic species are formed, acetate anion and hydronium.

Sugar C12H22O11: when it is placed in water, it is not properly dissociated but it is said to form hydrogen bonds in order to get dissolved in water, therefore, just one dissolved particle is formed.

In such a way, the substance having the larges number of moles of dissolved particles is aluminium hydroxide having four, by considering the same concentration for all the solutions, say 1 M or that so.

Regards.

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
