Ethanol (ethyl alcohol, C2H5OH) dissolves in water because the partial charges on the H and O atoms in the molecule interacts strongly with the partial charges on the atoms in water. Next, convert ml of H2O to kg of H2O (assume a density of 1.0 g/ml): 112.7 ml x 1.0 g/ml x 1 kg / 1000 g = 0.1127 kg. Application of Henry & # x27 ; s law of this feed is for personal use.

Many substances do not dissolve in water and that is because they are non-polar and do not interact well with water molecules. Soluble ionic compounds and strong acids are therefore both strong electrolytes, although the latter are molecular compounds that actually react with water, as indicated by the production of hydronium ion , or H 3 O + ( aq) , which is . 9 6 0 0 . Lost Restaurants Of Seattle, The (aq) shows that it is aqueous.The equation for C2H5OH and H2O sometimes isnt considered a chemical reaction since they can be separated by simple means (distillation). q 5.
