Answer:
The concentration of hydroxide ions is 3.02*10⁻³ M
Explanation:
The pOH (or OH potential) is a measure of the basicity or alkalinity of a contamination and is defined as the negative logarithm of the activity of the hydroxide ions. That is, the concentration of OH- ions:
pOH= -log [OH-]
The pOH has a value between 0 and 14 in aqueous solution, the solutions with pOH being greater than 7 being acidic, and those with pOH less than 7 being basic.
If pOH= 2.52 then
2.52= -log [OH-]
[OH-]= 3.02*10⁻³ M
<u><em>The concentration of hydroxide ions is 3.02*10⁻³ M</em></u>

Answer:
8
Explanation:
According to octet rule, they need 8 electrons in their outermost shell to be stable.But the maximum electrons that can be accomodated in each shell varies and the outermost electron of
in the outermost orbital of the given element depends upon it
Alright! Here are the answers:
1. C. Fluorine is more reactive than nitrogen because fluorine needs only one electron to fill its outermost shell.
2. Aluminum (Al)
Answer:
I want brainliest plz!!!
Explanation:
React excess copper metal with concentrated sulphuric acid or concentrated nitric acid until effervescence stops. Filter to remove excess copper. To the filtrate add either sodium carbonate or potassium carbonate to form copper (II) carbonate, to precipitate copper (II) carbonate wash and dry between filter paper
