Introduction to Lab #18…..

Without mysteries, life would be very dull indeed.

Page 2: Introduction to Lab #18….. Without mysteries, life would be very dull indeed

• Ten Numbered T-Tubes

• Each with a single substance

• Given a part of today and tomorrow to prepare

• No external reagents, testing materials.

• Smell and sight can be used

Page 3: Introduction to Lab #18….. Without mysteries, life would be very dull indeed

• All sets contain hydrochloric and sulfuric acid as well as ammonia and sodium hydroxide

• All others are nitrates, chlorides or sulfates some held in an acid environment

Page 4: Introduction to Lab #18….. Without mysteries, life would be very dull indeed

Preliminary Work

• Use your text, Appendix II, or the on-line resources wikipediawikipedia or webelementswebelements.

• NR, no reaction

• P, precipitate (followed by D if it dissolves)

• State colors if appropriate

• H, heat evolved

• G or S for gas or smoke formed
