Carla is using a fertilizer that contains nitric acid. how is nitric acid classified? strong acid weak acid strong base weak base

Nitric acid is classified as a strong acid.

Explanation:

Strong acid is defined as the acid which completely dissociates when dissolved in water. They have low pH. These releases ions in their aqueous states.

Weak acid is defined as the acid which does not completely dissociates when dissolved in water. They have high pH. These releases ions in their aqueous states.

Strong bases are defined as the base which completely dissociates when dissolved in water. They have high pH. These releases ions in their aqueous states.

Weak bases are defined as the basis which does not completely dissociates when dissolved in water. They have low pH. These releases ions in their aqueous states.

The equation for the dissociation of nitric acid is given by:

As, this compound is completely dissociating into its ions and also releasing ions. Hence, it is considered as a strong acid.

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
