Question
Chapter 8, Problem 37Q
Interpretation Introduction
Interpretation:
Names and chemical formulas for any five bases have to be given and any three observable properties generally associated with bases have to be listed.
Concept Introduction:
Strong Base: Bases that has strong attraction towards protons and accepts readily. Strong base forms weaker conjugated acid.
Weak Base: Bases that has little affinity towards protons. Weak base forms stronger conjugated acid.
According to Lewis concept of acid and bases,
Lewis acid is an electron pair acceptor.
Lewis base is an electron pair donor.

This price has been marked up 6% from the wholesale price that they pay to the manufacturer. You decide to use your knowledge of chemistry to produce your own ammonium phosphate and sell it to Home Depot at 5¢ below the wholesale price. You contact a packager, who agrees to package your product for 29¢ per bag. Ammonium phosphate is produced from ammonia (NH3) and phosphoric acid (H,PO4). Ammonia, in turn, can be produced at a 50% yield via the Haber process, using a mixture of hydrogen (H2) and nitrogen (N2) gases with an iron catalyst. Phosphoric acid is obtained from a naturally occurring mineral called fluorapatite, Cas(PO4)3F, by the following process: fluoroapatite is mixed with silica sand (SiO2) and coke (elemental carbon, C) in an electric furnace.
