Answer: It is a basic solution with pH =8.51
Explanation:
We were given that hydroxide ion concentration [OH-] as 3.26 x 10-6 M
But We know thar
[OH-] [H+] = 1 × 10^-14
To get the Hydrogen ion [H+] concentration, we have that
[H+] = 1 × 10^-14 M/[OH-]
= 1 × 10^-14 M/3.26 x 10-6 M
= 3.067 x 10^-9 M
But, pH = - log [H+]
Therefore,
pH = - log (3.067 x 10^-9)
pH=8.51
when pH > 7, The solution is basic, therefore a solution with pH =8.51 is basic.
Answer:
the answer is option (a).3
<span>The dependent variable is that which will respond to changes in the independent variable, which has been manipulated during the experiment. By doing so, this can lead to an understanding of whether or not the changes involved have a significant linkage or if they are due to some other factors.</span>
I mean I would just assume carbon 12 because the decimal is closer to 12 than 14
