I Would Sooner Fail Then Not Be Among the Greatest. John Keats

“I would sooner fail then not be among the greatest.” ~John Keats NAME:______DATE:______6.3 How do we determine if a compound is soluble? AHS Instructor Ms. Kasia Room 109 UNIT 6: SOLUTION AND GASES 6.3 Reading Tables F and G

DO NOW: Fill in the table in Important Vocabulary.

TABLE F IMPORTANT VOCABULARY DEFINITION DISSOLVES? FORMS WORD PRECIPITATE?

Solubility ------

Soluble

Insoluble

Precipitate ------

USING TABLE F TO PREDICT SOLUBILITY

SO HOW DO WE USE TABLE F? Example: Exceptions: Is NH4Cl soluble in H2O? Is AgCl soluble in H2O?

LET’S TRY SOME Directions: State whether the ionic compound will be soluble (precipitate does not form) or insoluble (precipitate forms) LiF PbCl2 HNO3 H2SO4 NaOH AgI Ca(OH)2 CaS AgBr (NH4)2S Fe3(PO4)2 KClO4 TABLE G “I would sooner fail then not be among the greatest.” ~John Keats IMPORTANT VOCABULARY WORD DEFINITION
