PH and pOH Formulas
Concentration Formulas
pH = -log[H30)
[H30*) = 10-PH
pOH = -log(OH)
[OH] = 10-POH
pH + POH = 14.00
[H3O+][0] = 1.0 10-14
What is the hydronium (H30*) concentration of a solution with a pH of 3.60?
A 2.5 x 10^M
B 3.0 x 10-M
C 4.0 x 10M
D.
45* 10-11M

The activity series is shown in the attached picture. if the element is below the other, then you can displace the other. following the activity series as a guide, the reactions are as follows: nickel and aluminum chloride3 ni + 2 alcl₃  → 3 nicl₂ + 2 albarium and copper bromideba + cubr  →  no reaction because cu is less oxidizable than bapotassium nitrate and aluminum3 kno₃ + al  → al(no₃)₃ + 3 ksodium phosphate and zincnaso₄ + zn  → znso₄ + na
