Calculate the ph solution with hydrogen ion concentration of 6.28×10^-6 moldm and 1×10^-5
To calculate the pH of a solution based on the hydrogen ion concentration, you can use the formula:
pH = -log[H+]
where [H+] represents the hydrogen ion concentration.
Case 1:
[H+] = 6.28×10^-6 mol/dm^3
pH = -log(6.28×10^-6)
pH = -(-5.2)
pH ≈ 5.2
Therefore, the pH of the solution with a hydrogen ion concentration of 6.28×10^-6 mol/dm^3 is approximately 5.2.
Case 2:
[H+] = 1×10^-5 mol/dm^3
pH = -log(1×10^-5)
pH = -(-4)
pH ≈ 4
Therefore, the pH of the solution with a hydrogen ion concentration of 1×10^-5 mol/dm^3 is approximately 4.
To calculate the pH of a solution given the hydrogen ion concentration (also known as the acidity or H+ concentration), you can use the equation:
pH = -log[H+]
where [H+] is the hydrogen ion concentration.
Let's calculate the pH for the first hydrogen ion concentration:
pH = -log(6.28×10^-6)
To solve this calculation, you need to take the negative logarithm (base 10) of the hydrogen ion concentration using a scientific calculator or a logarithmic table.
Using a scientific calculator:
pH = -log(6.28×10^-6)
≈ -(-5.2)
≈ 5.2
Hence, the pH of the solution with a hydrogen ion concentration of 6.28×10^-6 moldm is approximately 5.2.
Now, let's calculate the pH for the second hydrogen ion concentration:
pH = -log(1×10^-5)
Again, using a scientific calculator, we can solve this:
pH = -log(1×10^-5)
≈ -(-5)
≈ 5
Therefore, the pH of the solution with a hydrogen ion concentration of 1×10^-5 moldm is approximately 5.
