WATER AND THE SOLUTION PROCESS A A water

WATER AND THE SOLUTION PROCESS A. A water molecule consists of two atoms of _____ hydrogen and one atom of _______ oxygen united by _______ polar covalent bonds.

WATER AND THE SOLUTION PROCESS 1. The _____ polar nature of the water molecule allows for hydrogen bonding between ____ water molecules which contributes to some of water’s unique properties.

WATER AND THE SOLUTION PROCESS a. _______ Surface ______ tensionis the inward force or pull that tends surface ____ area to minimize the _______ of a liquid. Water has a relatively ____ high surface tension.

WATER AND THE SOLUTION PROCESS b. Water has a relatively _____ high boiling point due to the hydrogen bonding extensive ____ that occurs between water molecules.

WATER AND THE SOLUTION PROCESS

WATER AND THE SOLUTION PROCESS c. Hydrogen bonding holds water molecules in a hexagonal ____ arrangement in the solid form. This allows the solid form of water to occupy a greater volume and therefore smaller ______. density

WATER AND THE SOLUTION PROCESS aqueous solution is A. An ____ water that contains ____ dissolved substances.

WATER AND THE SOLUTION PROCESS B. The solution process depends on the _____ force of attraction between the solute _____, the thing getting dissolved, and the _______, solvent the thing doing the dissolving.

H H +Dissoc iationionic compound made A. When an _____ of ____ ions dissolves in water, the ions separate ____ from one another. This is called ______ dissociation and is the δ- δ+ O O δ+ δ- H H result of the strong attraction between the ions and the polar water molecules
