Did you Know? #5 - the amazing Vinegar

My Dear Sexy Readers,

For this week's Did you Know SSS - sexy short subject - we will have a look at the amazing usefulness of vinegar! We started this new series, appropriately with egg as the sexy short subject, going through egg as a baking ingredient, what's an emulsion, how to make a mayonnaise and why lemon juice or vinegar are added to it, but for our 5th episode:

Vinegar is the ideal house cleaning companion to get rid of lime scale

In fact, Vinegar has 1000s of use, like this website is explaining but what I'm interested in really is how vinegar works to remove lime scale.

Vinegar is a diluted (in water) version of acetic acid CH3COOH.
Limescale is a precipitate of calcium carbonate CaCO3

By adding them together:

 2 CH3COOH + CaCO3  

 (CH3COO)2Ca + H 20 + CO2

The resulting product (CH3COO)2Ca is soluble in water and therefore easy to wash away!
