Question 1: Why is it necessary to use water that is both distilled and at room temperature when doing dilutions?
Answer: It is necessary to use distilled water for dilutions in order to avoid any reactions or alterations caused by the minerals, or any other impurities, present in water that is not distilled. The water should be at room temperature, in combination with being distilled, so that it does not support any side reactions that may be caused by the increased or decreased temperature. Question 2: Outline an experimental procedure (step by step) by which 25.00 mL of 1.00 M HCl can be made from a stock solution of 5.00 M HCl.
Answer: The steps for preparing a 1M HCl from 5M HCl are as follows.
The required solution is prepared by diluting ...
