Question

What is the concentration of a HF solution with a PH of 2.3

Answer 1

Answer:
[H⁺] = 5.011 × 10⁻³ mol.L⁻¹

Step-by-step explanation:

The pH is converted into concentration of H⁺ as,

[H⁺] = 10^-pH

Where 10 is antilog,

So, putting values,

[H⁺] = 10⁻²·³

[H⁺] = 0.00501

Or,

[H⁺] = 5.011 × 10⁻³ mol.L⁻¹
