<span>There are a number of ways to express concentration of a solution. This includes molarity. Molarity is expressed as the number of moles of solute per volume of the solution. We calculate as follows:
</span>
2.5 M HCl = 2.5 mol HCl / L soln

0.306 mol HCl / 2.5 mol HCl/L son = 0.1224 L soln needed

M1V1 = M2V2
18 M(V1) = 2.5 M(0.1224 L)
V1 = 0.017 L of the 18 M solution

A solution has a pH of 2.5. what is the H+

romanna [79]

<u>Answer: </u>The concentration of $H^+$ in the solution is $3.16\times 10^{-3}M$

<u>Explanation:</u>

pH is defined as the negative logarithm of hydrogen ion concentration present in the solution.

$pH=-\log [H^+]$ .....(1)

We are given:

pH of solution = 2.5

Putting values in equation 1, we get:

$2.5=-\log [H^+]$

$[H^+]=10^{-2.5}$

$[H^+]=3.16\times 10^{-3}M$

Hence, the concentration of $H^+$ in the solution is $3.16\times 10^{-3}M$

Which change in oxidation number indicates oxidation? A) Ito +2 C +2 to -3 B) Ito -2 D) +3 to +2

tatuchka [14]

As there is the increase in Oxidation number from +1 to +2. Hence, the correct Option (A) i.e, 1 to +2,

<h3>What is Oxidation ?</h3>

Oxidation doesn't necessarily have anything to do with oxygen.

Oxidation occurs when an atom, molecule, or ion loses one or more electrons in a chemical reaction.
When oxidation occurs, the oxidation state or oxidation number of the chemical species increases.
Oxidation doesn't necessarily involve oxygen! Originally, the term was used when oxygen caused electron loss in a reaction.

Hence, Option (A) indicates the oxidation as there is the increase in Oxidation number from +1 to +2.
