Chemistry Ch-4

A substance in a solution that dissolves in water to yield a solution that conducts electricity.

Is the process by which an ionic compound, upon dissolution, breaks into constituent ions
NaCl...Na+ Cl-

Is the process by which a molecular compound forms ions when it dissolves
HCL...H+ Cl-

Strong electrolytes disassociate completely (ionic compounds) where weak electrolytes exist mostly as non ionized molecules

HCl, HBr, HI, HNO3, HCLO3,HCLO4,H2SO4

A light bulb is connected to a battery with electrodes submerged in water. Since water is not an electrolyte, meaning there are no ions that allow electricity to be conducted between the electrodes, the light bulb will not light. If a substance is added to the solution where there is disassociation, ions will disperse and allow the solution to conduct electricity from one electrode to the other, causing the light bulb to light. If the substance is a weak electrolyte where only few ions disperse and molecules remain, the light bulb will be weak.

Bronsted acids donate a proton (H+) and Bronsted bases receive a proton (H+). Sometimes take place in the gas phase.

Acids that each acid molecule has a respective number of protons (H+) to donate. Of the polyprotic acids, only sulfuric acid is the only strong electrolyte.

Indicates that amount moles of hydroxide per mole of compound are produced

Rxn between an acid and a base, usually produce salt and water.
