Strong and Weak Electrolytes

Strong and Weak Electrolytes Pure water does not conduct electricity because of a lack of free moving ions.

Strong and Weak Electrolytes An electrolyte is a substance that, when dissolved in water, produces free moving ions that allows the solution to conduct electricity. Add electrolyte 

Strong and Weak Electrolytes These are the strong electrolytes! Strong acids: HI, HBr, HCl, HNO3, and H2SO4 Strong bases: LiOH, NaOH, KOH, RbOH, CsOH Soluble salts: are found using Reference Table F NaCl, MgSO4, K2Cr2O7, NH4NO3, etc!

Strong and Weak Electrolytes These are the weak electrolytes! Weak acids: are all acids that are not strong Weak bases: are all bases that are not strong Insoluble salts: are found using Reference Table F
