aquous solutions and molarity Flashcards
What does (aq) mean the water is been used for
solvent
Is the larger component of a mixture the solvent or solute?
solvent
Is the smaller component of the mixture a solvent or solute?
solute
Is it true that the the solute dissolves the solvent to form a solution?
false
What happens when an ionic compound dissolves in water?
the compound breaks down into its structural case ions.
Why does water break ionic compounds into their structural case ions?
because water is a polar molecule and the charged ions have a strong attraction to the polar ends of the water molecules.
What type of bond is formed when the ions have been hydrated
dipole bond
Why are dipole bonds formed?
As the ionic solution crystallizes, some water remains attached to the ions.
What is the Water called that remains bound to a pure substance during crystallization called?
water of crystallization
What are salts without water crystallization called?
anhydrous salts
are covalently bonded molecular compounds soluble in water?
no
When can molecular compounds dissolve in water?
if the water can form stronger attachments to the molecules than the intermolecular forces within the molecular substances
What is a saturated solution?
a solution that no more of the particular solute can be dissolved in a given quantity of the solvent at the specified temperature.
What is a unsaturated solution?
A solution which contains less than this maximum amount of solute
How can the concentration of a solution be measured?
dividing the weight of solute in grams to the volume of solution.
