PH + pOH = 14
pOH=14-8=4
(OH-)=10^-4
PH scale is used to determine how acidic, basic or neutral a solution is
pH can be calculated using the H₃O⁺
ph can be calculated as follows
pH = - log[ H₃O⁺]
[H₃O⁺] = 1 x 10⁻⁹
pH = - log [1 x 10⁻⁹]
pH = 9
pH of solution is 9
Answer:The 2nd and 3rd one.
Explanation:
It has the same number of protons but different amount of nuetrons.
higher temp=faster motion
lower temp=slowed motion
