ELECTROLYSIS EXAM SCRIPT 2025/2026 QUESTIONS WITH
ANSWERS GRADED A+
✔✔oxidation - ✔✔gaining oxygen OR losing electrons
✔✔reduction - ✔✔losing oxygen OR gaining electrons
✔✔electrode - ✔✔conducting rod made of metal or graphite that carries the current
in/out of the electrolyte
✔✔solution - ✔✔an ionic solid dissolved in water
✔✔metal - ✔✔product formed at the negative electrode (cathode)
✔✔non-metal - ✔✔product formed at the positive electrode (anode)
✔✔Reason solid ionic compounds cannot conduct - ✔✔The ions have a fixed position
and cannot move
✔✔Reason molten substances can conduct - ✔✔The ions are free to move
✔✔Equation to show what happens at cathode - ✔✔Mg2+ + 2e- -> Mg
✔✔Equation to show what happens at anode - ✔✔2Cl- -> Cl2 + 2e-
✔✔Products of the electrolysis of molten sodium chloride - ✔✔sodium and chlorine
✔✔Products of the electrolysis of molten lead bromide - ✔✔lead and bromine
✔✔Products of electrolysis of molten aluminium oxide - ✔✔aluminium and oxygen
✔✔
✔✔Insulin - ✔✔Decreases sugar in the blood
✔✔Diabetes type 1 - ✔✔Insulin dependent, childhood onset, not producing enough
insulin
✔✔Diabetes type 2 - ✔✔Non insulin dependent, adulthood, *insulin resistant patients
✔✔Diabetes symptoms - ✔✔Frequent thirst; polydipsia, fragile blood vessels=bruising,
HBP, cardio problems, obesity, neuropathy
, ✔✔Groin: the gonads - ✔✔Secrete sex steroids. Male: androgens, female: estrogen +
progrsterone
✔✔FSH - ✔✔Changed testosterone to estrogen
✔✔LA - ✔✔Changes testosterone to progesterone
✔✔PCOS = Polycystic ovarian syndrome - ✔✔Ovaries contain cysts
✔✔Drugs that caused hair growth - ✔✔Dilatin, loestrin, minoxidil, prednisone, Premarin
✔✔Pre treatment and post Electrolysis - ✔✔FDA 70% alcohol, minimum 30% alcohol=
antiseptic
✔✔How to insert needle - ✔✔Always insert needle on the underside of the hair, parallel
to the hair, under the hair, size of the hair=size of needle. Never parallel or
perpendicular
✔✔Pseudofolliculitis barbe - ✔✔Razor bumps, Ingrown hairs
✔✔Hyper-pigmentation - ✔✔More active melanocytes= brown
✔✔Hypopigmentation - ✔✔Less melanocytes = white
✔✔2 factors of acne - ✔✔Can blood supply perform any rehealing, or will pathogenic
bacteria spread
✔✔insertion= when over insertion can cause.. - ✔✔good in HF can cause petechiae
✔✔shallow insertion causes - ✔✔higher % of over treatment, HF blow out and % of re
growth increases
✔✔miss follicle - ✔✔incorrect angle, increased pain and bruising, red scabs, % of
infection increases
✔✔miss pone - ✔✔sharp pain and bleeding, higher % of infection, petechiae
✔✔size of needle for female - ✔✔1-3
✔✔size of needle for male - ✔✔4-5
✔✔angle of inclination, hair doesnt exist at - ✔✔90 or 0 degrees
