Yes, it is possible. If you electrolyze MgSO4(aq), one of the products will be magnesium hydroxide. If you you add Hydrochloric acid to it you get magnesium chloride 2HCl(aq)+Mg(OH)₂(s)⟶MgCl₂(aq)+2H₂O(l), electrolyze that and you get magnesium and chlorine gas, the last step must be done outdoors Here's a useful link: https://www.youtube.com/watch?v=...

Aluminum oxide does not react with sulphates, even at high temperature. Anyway, aluminum sulphate does not support high temperatures : it is easily decomposed at around 700°C.

The solubility of sodium acetate is interesting (that means confusing!). Sodium acetate exists in two forms: anhydrous and trihydrate. When compounds exist in two forms like this, the solubilities, given in grams per 100 mL H20, are predictable: the hydrated form is much more soluble, because it is only partially the compound, and the other part is extra ...

I agree. This is a dangerous reaction and should not be tried without proper equipment, including a lab hood and fire extinguishing equipment. The fumes could be "just" droplets of sodium hydroxide solution. I've seen similar fumes involving hydrochloric acid, just by adding water to rinse out traces of concentrated acid (in a hood, of course). They may ...

Well sodium hydroxide(NaOH) is solid at room temperature but at high temperatures it can be converted to gases.This happens due to the fact that the molecules of NaOH gain so much energy that the intermolecular bonds (dipole-dipole) between 2 sodium hydroxide molecules are broken.The reaction of sodium with water is exothermic and produces lot of heat and ...

There are two show stoppers : $\ce{HCl}$ is strong acid, $\ce{CH3COOH}$ is weak acid. The reaction is practically completely shifted toward acetic acid and sodium chloride. Especially if acetic acid is diluted. $\ce{HCl}$ forms azeotrope with water with the maximal boiling point near 20% $\ce{HCl}$. If you heat the mixture, that would boil water and acetic ...

The vapor pressure of IPA at 2.4 degrees C is 1/4 that of its room temperature value (ref). The viscosity of IPA also increases dramatically as temperature cools to ~0 (ref). Could you simply conduct the evaporation with the same solution but in a colder environment? A normal household fridge should be in the right range for what you're looking for. The ...

Potassium permanganate solution tends to decompose with time, especially those which are not acidified. Just let an aqueous solution sit in a glass bottle and it will leave a brown film of tenacious manganese dioxide on the surface at room temperature. If water has any organic material, it will become brown and tap water is not pure water. It decomposes on ...
