    What is the purpose of the magnesium rod inside the water heater (bock)


    These anode rods, sometimes made from aluminum, prevent corrosion. The rod emits ions that line the tank and help prevent corrosion. The rod isn't solid magnesium or aluminum; it has an iron core. If your hot water smells of sulfur (rotten eggs), the anode rod has gone bad or there is a presence of hydrogen sulfur gas that is overwhelming the rod. Usually replacing the rod will stop the odor, but sometimes chlorination of the tank is necessary.

    How carboxylic acid different from mineral acid from ionization point of view


    • A mineral acid is defined as a water-soluble acid derived from inorganic minerals by chemical reaction as opposed to organic acids (e.g. acetic acid, formic acid).
    • Specifically: When you put sulfuric acid (H2SO4) into water, all of the molecules of acid will dissociate into two protons (H+) and sulfate anions (SO4 -2). There will be no intact molecules of H2SO4 in solution. When you put acetic acid (CH3COOH) into water, only some of the molecules dissociate into proton (H+) and acetate anions (CH3COO-). Some of the acetic acid molecules remain intact in solution.
    1. - Mineral acids are inorganic derivatives while carboxylic acid is a organic compound.
    2. - Mineral acids dissociate completely into ions while carboxylic acid dissociate partially.
    3. - Mineral acids show high conductivity while carboxylic acid shows low conductivity.
    4. - Mineral acids shows negligible in ionization on increasing the temperature while ionization of carboxylic acid increases with the increase of temperature.

    I tried concentrated sulfuric acid on the baked on aluminum foil and it didn't work after several minutes. Any other suggestions?


    Whatever happened? H2SO4 seems a bit drastic. What is the foil stuck to? Won't soaking with hot washing up water remove it?

    Can you please define these words for me? (science) Dissolved, solvent, solute, chemical reaction, concentrated, saturated, dilution & crystallisation.


    Dissolve - Think about how you put sugar into cofee, the sugar disolves into it, so you don't drink sugar pieces.

    Solvent - is a substance used to disolve stuff. For example acetone disolves plastic in general, so you do not use it to clean your camera.

    Solute - is a disolved substance. For example sugar in the cofee after it's been dissolved.

    Chemical reaction - When you mix 2 chemical elements that have an action one to another, a chemical reaction happens. For example if you put Sodium in water, it releases hidrogen and heat (often the hidrogen ignites)

    Concentrated - if you put too much sugar in your cofee, you say it's too concentrated.

    Saturated - the moment you add more sugar to the cofee, and it just does not dissolve, you say the cofee is saturated with sugar.

    Dilution - Reducing the concentration of a chemica. Adding more cofee to a saturated cup, is diluting it.

    Crystallization - is the natural or artificial process of formation of solid crystals in nature or lab. For example the formation of ice crystals. More on the wikipedia page HERE.
