Calculate the hydrogen ion concentration and the pH of each of the following solutions of strong acids.
(a) 0.00010 M HCl
if you could just explain how to do this that would be great!
thanks
First you recognize that HCl is a strong acid and ionizes completely; therefore,
HCl + H2O ==> H3O^+ + Cl^-
So if you start with 0.00010 M HCl,knowing it is ionized completely, the H3O^+ must be 0.00010.
pH = -log(H^+) = -log(0.00010) = -(-4.0) = 4.0 and pH = 4.0
Sure! To calculate the hydrogen ion concentration (H+) and pH of a solution of a strong acid, you can use the following steps:
Step 1: Determine the initial concentration of the strong acid. In this case, it is given as 0.00010 M HCl.
Step 2: Since HCl is a strong acid, it dissociates completely in water to form H+ and Cl- ions. Therefore, the hydrogen ion concentration (H+) in the solution will be equal to the initial concentration of the acid, which is 0.00010 M.
Step 3: To calculate the pH, you can use the equation: pH = -log[H+]. Plugging in the value of H+ (0.00010 M) into the equation, we get pH = -log(0.00010).
Now, let me add a bit of humor to lighten things up:
Calculating the pH of a strong acid solution? Acid you need is a sense of humor! So, let's get this reaction going!
pH = -log(0.00010)
Using my incredible computational skills, I have calculated that the pH of the solution is approximately 4. Let's keep things on the 'acidic' side and laugh our way through the calculations!
I hope that helps! If you have any more questions, feel free to ask.
To calculate the hydrogen ion concentration and pH of the solution, we need to use the equation for the dissociation of the strong acid. In this case, the strong acid is HCl, which completely dissociates into H+ and Cl- ions.
The balanced equation for the dissociation of HCl is: HCl -> H+ + Cl-
Since the concentration of HCl is 0.00010 M, the concentration of H+ ions will also be 0.00010 M. This is because HCl dissociates in a 1:1 ratio, meaning that for every mole of HCl, there is one mole of H+ ion.
The pH is a measure of the acidity of the solution and is defined as the negative logarithm (base 10) of the hydrogen ion concentration.
To calculate the pH, take the negative logarithm (base 10) of the hydrogen ion concentration:
pH = -log[H+]
Using the concentration of H+ ions we calculated earlier:
pH = -log(0.00010)
pH โ 4.0
So, the hydrogen ion concentration of the 0.00010 M HCl solution is 0.00010 M and the pH of the solution is approximately 4.0.
To calculate the hydrogen ion concentration and the pH of a strong acid solution, you need to use the formula for calculating pH:
pH = -log[H+]
where [H+] represents the hydrogen ion concentration.
In this case, we are given that the concentration of HCl is 0.00010 M. Since HCl is a strong acid, it completely dissociates in water, meaning that all of the HCl molecules will release an H+ ion. Thus, the hydrogen ion concentration is equal to the concentration of HCl.
So, the hydrogen ion concentration ([H+]) for the given solution of 0.00010 M HCl is 0.00010 M.
To calculate the pH, we substitute the hydrogen ion concentration ([H+]) into the pH formula:
pH = -log(0.00010)
Using a calculator, evaluate -log(0.00010) to find the pH. The pH for the given solution of 0.00010 M HCl will be the negative logarithm of the hydrogen ion concentration.
