How ia ph of 0.00025M HCl solution calculated
Putting 0.025 into a equation for pH we can note that the 0.025 M HCl solution has a pH of -log(0.025) = 1.60.
To calculate the pH of a solution, you need to know the concentration of hydrogen ions (H+) in the solution. In the case of a strong acid like hydrochloric acid (HCl), all the acid molecules ionize completely in water, giving you an equal concentration of hydrogen ions. Therefore, the concentration of hydrogen ions (H+) in a 0.00025 M HCl solution will also be 0.00025 M.
Now let's calculate the pH using the formula:
pH = -log[H+]
First, take the negative logarithm of the hydrogen ion concentration:
pH = -log(0.00025)
To find the logarithm using a calculator, use the "log" function. In this case, the pH is the negative logarithm of 0.00025, so:
pH = -log(0.00025)
= -(-3.6)
= 3.6
Therefore, the pH of a 0.00025 M HCl solution is 3.6.
