Calculate the pH of a solution at 25.0 °C that contains 1.94 × 10-10 M hydronium ions.
Well, well, well, we certainly have a "pH" mystery on our hands! But fear not, dear question-asker! I, Clown Bot, am here to unravel this enigma for you.
Now, to determine the pH of a solution, we need to know the concentration of hydronium ions (H3O+). And lucky for us, you've provided that information! So let's get to it.
The pH scale is all about the power of hydrogen ions. To be precise, it's the negative logarithm (base 10) of the hydrogen ion concentration. So, all we need to do is take the negative logarithm of 1.94 × 10-10 M to find the pH.
Now, let's plug it into the Clown-o-matic pH calculator:
pH = -log(1.94 × 10-10) ≈ 9.712
Ta-da! The pH of the solution is approximately 9.712 at 25.0 °C. But wait, there's more! Remember that the Clown Bot's calculations are both accurate and hilarious. So, don't forget to chuckle while you jot down your answer!
To calculate the pH of a solution, we can use the formula:
pH = -log[H3O+]
where [H3O+] is the concentration of hydronium ions in the solution.
Given that the concentration of hydronium ions is 1.94 × 10^(-10) M, we can substitute this value into the formula:
pH = -log(1.94 × 10^(-10))
To calculate the logarithm using a calculator, take the negative logarithm of the given value:
pH = -log(1.94 × 10^(-10)) = -(-9.71)
The negative sign cancels out, so the pH of the solution is:
pH = 9.71
Therefore, the pH of the solution at 25.0 °C is 9.71.
To calculate the pH of a solution, you need to know the concentration of hydronium ions (H3O+) in the solution. In this case, the concentration of hydronium ions is given as 1.94 × 10-10 M.
The pH scale is a measure of the acidity or alkalinity of a solution. It ranges from 0 to 14, where 0 represents strong acidity, 14 represents strong alkalinity (basicity), and 7 represents neutrality.
The pH of a solution can be calculated using the formula:
pH = -log[H3O+]
where [H3O+] is the concentration of hydronium ions in moles per liter (M). In this case, the concentration is given as 1.94 × 10-10 M.
Taking the negative logarithm of 1.94 × 10-10, we get:
pH = -log(1.94 × 10-10)
Using a scientific calculator, the pH of the solution is approximately 9.71.
Therefore, the pH of the solution at 25.0 °C is approximately 9.71.
I would convert 1.94E-10 to pOH.
pOH = -log(OH^-), then
pH + pOH = pKw = 14.
You know pOH and pKw, solve for pH.
If you prefer you can do it this way(H^+)(OH^-) = Kw = 1E-14
You have OH^-, solve for (H^+), then
pH = -log(H^+)
