PH scale is used to determine how acidic or basic a solution is.
pH can be calculated as follows;
by knowing the ph we can calculate pOH
pH + pOH = 14
pOH = 14 - 8.1
pOH = 5.9
pOH is used to calculate the hydroxide ion concentration
pOH = -log[OH⁻]
[OH⁻] = antilog(-pOH)
[OH⁻] = 1.26 x 10⁻⁶ M
therefore hydroxide ion concentration is 1.26 x 10⁻⁶ M
The longest chain of carbons will contain the highest number of carbon atoms.
Explanation:
question 3 - the longest chain have 7 carbon atoms
question 4 - the longest chain have 8 carbon atoms
question 1 - the longest chain have 5 carbon atoms
You may find in the attached picture the longest chain colored in blue for each of the compounds.

Answer:
By Filtration using Filter Paper
Explanation:
Aluminium Powder is made from Aluminium with the help of mechanical means. This powder is mainly used in paints, cosmetics, fingerprint powders, thermite, rocket fuels e.t.c.
Also, Aluminium Powder is insoluble in water and organic solvents. Therefore, when mixed in Ethanol it will form a suspension. The Aluminium Powder can therefore be easily separated by simple Filtration using Filter paper.
