Answer:
Explanation:
Because the experiment has an different independent and dependent variable and each part has a different result of what type of copper or what type of control you are using for you experiment.
PLS MARK BRAINLIEST IF CORRECT I WORKED HARD ON THIS ANSWER,HAVE A NICE DAY/NIGHT <3
I believe the answer is B. Definitely not D or A, and C doesn't makes sense.
I think it's - log [H3O^+]
P.S. the 3 is a lowered exponent
The pH scale for acids and bases ranges from 1 - 14. The answer is letter C. The rest of the choices do not answered the question above. There are quite a few
relationships between [H+] and [OH−]
ions. And because there is a large range of number between 10 to 10-15
M, the pH is used. pH = -log[H+] and pOH = -log[OH−]. In aqueous solutions, [H+
][OH- ] = 10-14. From here we can derive the values of each concentration.
-log[H+ ] + -log[OH- ] = -log[10-14]
pH + pOH = 14
So pH = 14 – pOH and pOH = 14 –
pH
