What is the ph of a koh solution that has [h+] = 1.87 × 10–13 m?

pH = 12.73

Explanation:

pH of a solution is defined as the log to base 10 of the hydrogen ion (H+) concentration of the solution.

In the question above,

H+ = 1.87×10⁻¹³M

pH = -log[H+]

pH = -log(1.87×10⁻¹³)

pH = -(-12.73)

pH = 12.73

The pH of a 1.87×10⁻¹³ KOH solution is 12.73

the answer is b & c i believe : )

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
