The seasons. This is because when Earth is on an angle, different parts of the world get different amounts of heat, making temperatures different, and therefore changing the environment.
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⁺] = ![10^{-pH}](https://tex.z-dn.net/?f=10%5E%7B-pH%7D)
Given that, pH = 3.75
So concentration of H⁺ ion will be calculated as:
[H⁺] = ![10^{-3.75}](https://tex.z-dn.net/?f=10%5E%7B-3.75%7D)
[H⁺] = 1.7 × 10⁻⁴M
Hence concentration of H⁺ ion is 1.7 × 10⁻⁴M.
