The pH of a solution with a concentration of H+ equal to 10-4 is __________ Blank 1. Is this solution acidic, basic/alkaline, or neutral?
The pH of a solution with a concentration of H+ equal to 10-4 is 4.
This solution is considered acidic because pH values below 7 indicate acidity.
To find the pH of a solution with a concentration of H+ equal to 10-4, we can use the formula:
pH = -log[H+]
Plugging in the value [H+] = 10-4 into the formula, we have:
pH = -log(10-4)
Now we can calculate the pH step-by-step:
Step 1: Take the logarithm of 10-4:
log(10-4) = -4
Step 2: Negate the result:
-(-4) = 4
Therefore, the pH of the solution with a concentration of H+ equal to 10-4 is 4.
To determine whether the solution is acidic, basic/alkaline, or neutral, we can refer to the pH scale. On the pH scale, pH values below 7 indicate acidity, pH values above 7 indicate alkalinity, and a pH of 7 is neutral.
Since the pH of the solution is 4 (which is below 7), the solution is acidic.
