FIND THE PH IN WHICH HYDROGEN ION CONCENTRATION IS 6.38*10-6 MOL/DM CUBE
pH = - log (H^+) = - log (6.38E-6) = ?
To find the pH in which the hydrogen ion concentration is 6.38*10^-6 mol/dm^3, you can use the equation for pH, which is defined as the negative logarithm (base 10) of the hydrogen ion concentration.
Mathematically, it can be expressed as:
pH = -log10[H+]
Given the hydrogen ion concentration of 6.38*10^-6 mol/dm^3, we can substitute it into the equation to find the pH:
pH = -log10(6.38*10^-6)
Next, perform the calculation:
pH = -log10(6.38 * 10^-6)
Using a calculator, the value of this expression is approximately 5.197.
Therefore, the pH in which the hydrogen ion concentration is 6.38*10^-6 mol/dm^3 is approximately 5.197.
To find the pH at which the hydrogen ion concentration is 6.38 × 10^(-6) mol/dm³, you can use the following equation:
pH = -log[H+]
Where [H+] represents the hydrogen ion concentration.
First, substitute the given hydrogen ion concentration into the equation:
pH = -log(6.38 × 10^(-6))
Now, let's solve this using a scientific calculator or an online logarithm calculator:
pH ≈ -(-5.195)
pH ≈ 5.195
Therefore, the pH at which the hydrogen ion concentration is 6.38 × 10^(-6) mol/dm³ is approximately 5.195.
