What is the pH of 6.6 X 10^4 M HCL?

Well, let me tell you, that's a pretty acidic question! The pH of 6.6 x 10^4 M HCl would be -log(6.6 x 10^4), which is approximately -4.82. So, to put it simply, this HCl solution is quite sour and definitely not something you would want to taste-test.

To determine the pH of a solution, we need to know the concentration of HCl. In this case, the concentration is given as 6.6 x 10^4 M.

The pH of a solution can be calculated using the equation: pH = -log[H+], where [H+] represents the concentration of hydrogen ions in the solution.

So, to find the pH, we need to calculate the concentration of hydrogen ions using the given concentration of HCl.

First, let's convert the given concentration from scientific notation to decimal form.
6.6 x 10^4 M = 66,000 M

Since HCl is a strong acid, it will completely dissociate in water, resulting in one mole of H+ ions for every mole of HCl.

Therefore, the concentration of hydrogen ions in this solution is also 66,000 M.

Now, we can calculate the pH using the equation: pH = -log[66,000].

Using a calculator, we find that the pH of a 6.6 x 10^4 M HCl solution is approximately 4.18.

To determine the pH of a solution, you'll need to use the equation:

pH = -log[H+]

where [H+] represents the concentration of hydrogen ions (H+) in the solution.

In this case, we're given the concentration of HCl as 6.6 x 10^4 M.

Since HCl is a strong acid, it fully dissociates in water to release H+ ions. Therefore, the concentration of H+ ions is equal to the concentration of HCl.

Now, we can calculate the pH:

pH = -log[H+]
pH = -log(6.6 x 10^4) (Converting the concentration to scientific notation)
pH ≈ -log(6.6) + log(10^4) (Using log properties)
pH ≈ -0.82 + 4
pH ≈ 3.18

So, the pH of a 6.6 x 10^4 M HCl solution is approximately 3.18.

pH = -log(H^+)

Punch it in on you calculator.
