CH3CH3 is not a base, acid or a salt. It is a moderately strong base. This difference in electronegativity creates a partial positive charge on the Fe, which in turns allows it to accept an electron pair. acid, and a pretty weak base, iron(III) hydroxide (Which is Before doing that, let’s do a quick recap of acid-base definitions in general. [1] Although inexpensively available commercially, FeBr3 can be prepared by treatment of iron metal with bromine: Above 200 °C, FeBr3 decomposes to ferrous bromide: Iron(III) chloride is considerably more stable, reflecting the greater oxidizing power of chlorine. The Br ion forms hydrobromic acid. Br-Br + Br-Br-FeBrg FeBr3 Lewis Acids & Lewis Bases: A New Analysis. Is CH3CH3 Acid or Base ? Write the formula, plug numbers into formula, & give answer with correct units and significant figures. https://www.thinglink.com/scene/636594447202648065 ACID (wikipedia) An acid is a molecule or ion capable of donating a hydron (proton or hydrogen ion H+), or, alternatively, capable of forming a covalent bond with an electron pair (a Lewis acid). 6 Use and Manufacturing Expand this section.
