Pt.1 predict whether soluble or insoluble.
Pt 2. Miscible or immiscible
Pt 3 and beyond- answering questions
1. For each of the following pairs of solute and solvent, predict whether the solute would be soluble or insoluble. After making your predictions, you can check your answers by looking up the compounds in The Merck Index or the CRC Handbook of Chemistry and Physics. Generally, The Merck Index is the easier reference book to use. If the substance has a solubility...
