How do boiling water and electrolysis compare
Weba) Boiling water and electrolysis of water both break covalent bonds b) Boiling water breaks covalent bonds while electrolysis breaks intermolecular attractions c) Boiling … WebIf water behaved as a normal polar molecule it would have boiled at about - 100 C (shown in red). The other molecules are slightly polar and show the increase in boiling point with molecular weight which is normal. Instead, water boils at +100 C, which is very abnormal.

Webdistillation, electrolysis, reverse osmosis, freeze separation. compare pure water and seawater in terms of their boiling points. seawater boils at a temperature 0.6°C higher than pure water. ... why are the freezing and boiling points of water higher than would be expected for a compound of its molecular makeup. WebAt temperatures around the water boiling point, these solutes stay in the liquid. Now the total pressure in the liquid and the air at the boundary are the same- otherwise one would push the other into a smaller space. Part of the pressure in the liquid comes from the solutes, not the water. So the pressure due to the water alone is reduced ...
WebWater electrolysis is an electrochemical process in which electricity is used to split water into two gases, hydrogen and oxygen. The overall reaction of water electrolysis is expressed as.
