Answer : The pH of a solution is, 7.28
Solution : Given,
Concentration of hydronium ion, =
pH : It is defined as the negative logarithm of hydronium ion concentration or hydrogen ion concentration.
Now put the value of hydronium ion concentration in this expression, we get the pH of the solution.
Therefore, the pH of a solution is, 7.28
Answer:
0.123 mol
Explanation:
Step 1: Convert 250 °C to Kelvin
We will use the following expression.
K = °C + 273
K = 250 + 273 = 523 K
Step 2: Calculate the number of moles of gas (n)
A gas occupies a container with volume (V) 3.2 L at a temperature (T) of 523 K and pressure (P) of 1.65 atm. We can calculate the number of moles of the gas using the ideal gas equation.
P × V = n × R × T
n = P × V / R × T
n = 1.65 atm × 3.2 L / (0.0821 atm.L/mol.K) × 523 K = 0.123 mol

Answer:
2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃
Explanation:
When a base as sodium hydroxide (NaOH) reacts with an acid as sulfurous acid (H₂SO₃), the H⁺ of the acid will produce with the OH⁻ of the base H₂O. Te complementary ions will produce the respective salt (Na₂SO₃):
NaOH + H₂SO₃ → H₂O + Na₂SO₃
To balance the sodiums:
2NaOH + H₂SO₃ → H₂O + Na₂SO₃
And the hydrogens:
<h3>2NaOH + H₂SO₃ → 2H₂O + Na₂SO₃</h3><h3 />
And this is the complete reaction for this neutralization reaction.
