What are the concentrations of hydroxide and hydronium ions in a solution with a pH of 8.3?

Chemistry
1 answer:
Margarita [4]3 years ago
5 0

Answer:

The hydroxide concentration is 2*10^-6 M

The hydronium concentration is 5*10^-9 M

Explanation:

Step 1: Data given

pH = 8.3

Step 2: Calculate [H+]

pH = 8.3 = -log [H+]

[H+] = 10^-8.3 = 5*10^-9 M

[H+] = [H3O+] = 5*10^-9 M

Step 3: Calculate pOH

pH + pOH = 14

pOH = 14 -pH = 14 - 8.3 = 5.7

Step 4: Calculate concentration of hydroxide

pOH = -log [OH-] = 5.7

[OH-] = 10^-5.7 = 2*10^-6 M

The hydroxide concentration is 2*10^-6 M

The hydronium concentration is 5*10^-9 M

True or false: the most easily ionizable elements are the most electronegative.
ehidna [41]
<span>False, This is because when you can easily ionize and atom or the chances of it being ionizable are quite high, it means that that particular atom have very low ionization potential that is the reason why it was easily ionizable An atom with a high ionization power and a firmly negative electron fondness will both pull in electrons from different particles and oppose having its electrons taken away; it will be an exceedingly electronegative molecule.</span>

How many unpaired electrons are in the c 2 + ​ ion?
sladkih [1.3K]
Atomic number of C is 6. Hence, there are 6 electrons in carbon.

The electronic configuration of carbon is 1s2, 2s2, 2p2

Here, there are 2 unpaired electron. However, C2+ ions have 2 electrons less as compared to C.

Hence, electronic configuration of C 2+ ion is 1s2, 2s2. All the electrons are paired in this system. So there are no unpaired electrons in C 2+ ion.
