Question

The concentration of nitrate ion in a solution that contains 0.800 m aluminum nitrate is _______ m.

Answer 1

The concentration of nitrate ion in a 0.800 M solution of aluminum nitrate is 0.800 M.

Step-by-step explanation:

The concentration of nitrate ion in a solution that contains 0.800 M aluminum nitrate can be determined by understanding the stoichiometry of the compound. The concentration of nitrate ion in a solution that contains 0.800 M aluminum nitrate can be determined by understanding the stoichiometry of the compound. In aluminum nitrate, the formula is Al(NO3)3, which means there are three NO3- ions for every one Al3+ ion. Since the molarity of aluminum nitrate is 0.800 M, the concentration of nitrate ion is also 0.800 M.In aluminum nitrate, the formula is Al(NO3)3, which means there are three NO3- ions for every one Al3+ ion. Since the molarity of aluminum nitrate is 0.800 M, the concentration of nitrate ion is also 0.800 M.

Answer 2

First, we will write the equation:
Al(NO3)3 ...............> Al3+ + 3 NO3 -
We can notice that:
one mole of aluminium nitrate yields 3 moles of nitrate .
Therefore, to know the concentration on nitrate in 0.8 moles of aluminium salt, we will simply use cross multiplication as follows:
concentration of nitrate = (0.8 x 3) / 1 = 2.4 m.

The concentration of nitrate ion in a solution that contains 0.800 m aluminum nitrate is 2.4 m.
