30. What is the Bronsted base of H2PO4- + OH- ⟶HPO42- + H2O?

Chemistry

romanna [79]2 years ago

Answer:

OH⁻ is the Bronsted-Lowry base.

Explanation:

A Bronsted-Lowry base is a substance that accepts protons. In the chemical equation, OH⁻ accepts a proton from H₂PO₄⁻ to become H₂O. H₂PO₄⁻ would be a Bronsted-Lowry acid because it donates a proton to OH⁻ and becomes HPO₄²⁻.

Hope that helps.

Which of the following ions is formed when a base is dissolved in a solution?
Aneli [31]

Answer:

\huge\boxed{\sf OH-}

Explanation:

<u>According to Arrhenius concept of acid and base:</u>

"When a base in a solution, produces/yields OH- (Hydroxide) ions."

So, when a base is dissolved in a solution, it produces OH- ions.

<u>For example:</u>

NaOH ⇄ Na⁺ + OH⁻ (So, it is a base)

\rule[225]{225}{2}

Hope this helped!

Calculate the number of moles of solute present in 185.0 mL of a 1.50 mol/L solution of HCl.
____ [38]

Answer:

0.278 mol HCl

Explanation:

We currently have 185.0 mL of a 1.50 mol/L solution of HCl. We want to find the number of moles there are.

Based on the given information, our volume is 185.0 mL and our molarity is 1.50. Because molarity is defined as moles / Litre, we can easily find the moles given volume by multiplying molarity by volume.

First, though, we must convert millilitres to litres. There are 1000 mL in 1 L, so divide 185.0 by 1000:

185.0 / 1000 = 0.185 L

Now, multiply 0.185  by 1.50:

0.185 L * 1.50 mol/L = 0.278 mol HCl

Thus the answer is 0.278 mol HCl.
