Final answer:

The pH of the aqueous solution is 1.12.

Step-by-step explanation:

The equation pH = -log[H+] must be used to determine the solution's pH. Considering that the arrangement has [H+] = 0.075 M, we can compute the pH as follows:

1. Substitute the worth of [H+] into the situation pH = - log[H+].

2. Compute the negative logarithm of 0.075:

pH = -log(0.075)

3. Utilize a mini-computer to track down the logarithm:

pH ≈ 1.12

The pH of an aqueous solution can be calculated using the equation pH = -log[H+]. In this case, the hydrogen ion concentration is given as 0.075 M. To find the pH, we take the negative logarithm of 0.075:

pH = -log(0.075) = 1.12

Therefore, the pH of the solution is 1.12, which corresponds to option b.

Answer:

1.131

Step-by-step explanation:

pH=-logH^+

H^+=0.074

pH=-log 0.074

pH=1.131
