What is the hydronium ion concentration in an aqueous hydrobromic acid solution with a pH of 4.530?

Chemistry

Aloiza [94]3 years ago

Answer:

2.951 × 10⁻⁵ M

Explanation:

Let's consider the acid reaction of hydrobromic acid according to Brönsted-Lowry acid-base theory.

HBr(aq) + H₂O(l) ⇒ Br⁻(aq) + H₃O⁺(aq)

Given the pH = 4.530, we can calculate the concentration of the hydronium ion using the following expression.

pH = -log [H₃O⁺]

[H₃O⁺] = antilog -pH = antilog -4.530 = 2.951 × 10⁻⁵ M

Calculate the number of grams of solute in 814.2mL of 0.227 M calcium acetate
kiruha [24]

Answer:

Mass = 29.23 g

Explanation:

Given data:

Volume of solution = 814.2 mL 814.2/1000 = 0.8142 L)

Molarity of solution = 0.227 M

Mass of solute in gram = ?

Solution:

Molarity = number of moles / volume in L

By putting values,

0.227 M = number of moles / 0.8142 L

Number of moles = 0.227 M × 0.8142 L

Number of moles = 0.184 mol

Mass in gram:

Mass = number of moles × molar mass

Molar mass of calcium acetate = 158.17 g/mol

Mass = 0.184 mol × 158.17 g/mol

Mass = 29.23 g
