Canadian chemists have developed a modern variation ofthe 1899 Mond process for preparing extremely pure metallicnickel. A sample of impure nickel reacts with carbon monoxideat 50°C to form gaseous nickel carbonyl, Ni(CO)₄.(a) How many grams of nickel can be converted to the carbonylwith 3.55 m³ of CO at 100.7 kPa?(b) The carbonyl is then decomposed at 21 atm and 155°C to pure (>99.95%) nickel. How many grams of nickel are obtainedper cubic meter of the carbonyl?(c) The released carbon monoxide is cooled and collected forreuse by passing it through water at 35C. If the barometric pres-sure is 769 torr, what volume (in m³) of CO is formed per cubicmeter of carbonyl?

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
