A chemist is using a solution of HNO₃ that has a pH of 3.75. what is [H⁺] for the solution is 1.7 × 10⁻⁴M.
<h3>How do we calculate the [H⁺]?</h3>Concentration of H⁺ ion will be calculated by using the below equation of pH as:
pH = -log[H⁺]
or [H⁺] =
Given that, pH = 3.75
So concentration of H⁺ ion will be calculated as:
[H⁺] =
[H⁺] = 1.7 × 10⁻⁴M
Hence concentration of H⁺ ion is 1.7 × 10⁻⁴M.

Answer:
Equilibrium concentrations of the gases are
Explanation:
We are given that for the equilibrium
Temperature,
Initial concentration of
We have to find the equilibrium concentration of gases.
After certain time
2x number of moles of reactant reduced and form product
Concentration of
At equilibrium
Equilibrium constant
Substitute the values
By solving we get
Now, equilibrium concentration of gases
