Which reaction most accurately represents the dissociation of nitrous acid (hno2) in water?
yanalaym [24]

When nitrous acid (HNO₂) dissociates in water (H₂O), the reaction that best captures this process is:

                HNO₂ (aq.) + H₂O ↔  H₃O⁺ (aq.) + NO₂⁻ (aq.)

How does one know about HNO₂?

  • The chemical designation for nitrous acid is HNO₂, and it is a monoprotic acid. Three elements—hydrogen(H), oxygen(O), and nitrogen(N), all compose it.
  • It is highly fragile in nature and only occurs in solutions.
  • It is employed to convert amines into diazonium salts.

Is HNO₂ a basic or an acid?

Acidity is assigned to nitrous acid (HNO₂). Once dissolved in water, it gives out H+ ions. Acid is a chemical that produces H+ ions in a water-based solution or gives the protons to other molecules.

Thus, HNO₂ is acid because it causes a mixture of water to contain H+ ions. In a 10 mM concentration, it possesses a pH of 2.67.

Calculate the osmotic pressure of a magnesium citrate laxative solution containing 25.5 g of magnesium citrate in 244 mL of solu
Vera_Pavlovna [14]

Answer:

The answer to your question is π = 12.47 atm

Explanation:

Data

mass of Magnesium citrate = 25.5 g

volume of solution = 244 ml

temperature = 37°C

molar mass C₆H₆MgO₇ = (12 x 6) + (1 x 6) + (24 x 1) + (16 x 7) = 214 g

Osmotic pressure = π = ?

Process

1.- Calculate the moles of magnesium citrate

                         214 grams ----------------- 1 mol

                          25.5 grams ---------------  x

                           x = (25.5 x 1)/214

                           x = 0.119

2.- Calculate molarity

Molarity = moles/volume

Molarity = 0.119/0.244

Molarity = 0.49

3.- Calculate osmotic pressure

π = MRT

π = (0.49)(0.0821)(37 + 273)

π = (0.49)(0.0821)(310)

π = 12.47 atm
