Question

the names and chemical formulae of some chemical compounds zinc iodide methanol E objective Knowledge Check The names and chemical formulae of some chemical compounds are written in the first two columns of the table below. Each compound Imagine that a few tenths of a each compound is dissolved in alter water, Then, write dawn in the third column of the table the chemical formula of the major chemical species that will be present of know water formula for water (HM). in this solution. For example, Note: major chemical species are those present in concentrations greater than 10 mel/L. 5 6 7 8

Explanation / Answer

ZnI2 -----> Zn+2 + 2I-

Major species will be I- ions

CH3OH when dissolved in water , it will ionize very lightly

So, Major species is CH3OH

ZnBr2 ----> Zn+2 + 2Br-

It will fully ionize

So, Major species is Br-
