Would the following procedural changes cause the experimentally determined mass percent NH3 in Ni(NH3)nCl2 to be too high, too low, or unchanged? Briefly explain each answer.

a) Describe the color and apperance changes you observed when you dissolved NiSO4 * 6H2O in distilled water and then added NH3 solution.

b) Descrie the color and apperance changes you observed when you dissolved Ni(NH3)nCl2 in distilled water and then added NH3 solution.

c) Suggest an explanation for the changes you described in a) and b).

Procedure Reaction 1: Dissolving the Copper 1. Obtain a clean, dry, glass centrifuge tube. 2. Place a piece of copper wire in a weighing paper, determine the mass of the wire and place it in the centrifuge tube. The copper wire should weigh less than 0.0200 grams. 3. In a fume hood, add seven drops of concentrated nitric acid to the reaction tube so that the copper metal dissolves completely. Describe your observations in the lab report. (Caution, Concentrated nitric...

Acid-Base Behavior In addition to following the general safety rules, chemicals need to be handled properly. In particular, two very important classes of compounds called acids and bases require special attention. These compounds are commonly used reagents in the laboratory; therefore, understanding their proper disposal is beneficial. Physical differences between acids and bases can be detected by the some of the five senses, including taste and touch. Acids have a sour or tart taste and can produce a stinging sensation...

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...
