Ans: Component of solution that has a lesser concentration
What trades do solutions exhibit?
Ans: The homogenous, the components of a solution are
dispersed on a molecular scale, the dissolve salute, and a
solution will not settle out or separate from solvent
What happens when an ionic compound is mixed with water
Ans: the different ions of the compound are pulled apart , or
dissolved, by the water molecules.
ion-dipole attraction
Ans: electrostatic attraction between an ion and a polar
molecule
Electrolyte
Ans: Substances that produce ions in solution when dissolved
Non-electrolytes
Ans: substances that form no ions in water and cannot conduct
electricity

Strong electrolytes
Ans: If the physical or chemical process generates is 100%
efficient
Weak electrolytes
Ans: Small fraction of dissolve, substance undergoes I am
productivity process
Precipitation reaction
Ans: Went to aqua solutions are mixed to form an insoluble
product
Endothermic
Ans: (of a chemical reaction or compound) occurring or formed
with absorption of heat
Are ionic compounds endothermic
Ans: Yes, Ionic compounds with stronger bonds require greater
amount of energy to separate anions and cations (higher
melting point)
