An aspirin product on the market claims to use magnesium hydroxide, Mg(OH)2, as a buffering agent. How could you verify whether magnesium ions are present?
Chemistry Covalent Substances?
For homework, I have to pick 3 substances that I think are covalent substances and also explain (briefly) why I think these substances are covalent. I need help finding some substances.
In the electrolysis of aqueous copper sulphate, i know that copper is preferred for discharge at the cathode because it is less reactive than hydrogen but i don't understand why OH- is preferred to be discharged instead of SO4(2-)
