What are the properties of water? In mini-lab 1‚ water was dropped onto the flat surface of a penny until the surface tension of the water was broken. 50 drops were able to be put onto the penny surface‚ with 51 drops of water being the point at which the hydrogen bonds of the water droplets that had created surface tension prior to drop number 51 failed to keep the surface tension‚ and the water spilt over the edges of the penny. This number of drops on the penny‚ 50‚ was possible because of cohesion

A. Goal and Purpose: Session 1: In this lab‚ we will achieve a simple Friedel-Crafts alkylation of anthracene. The choice of anthracene as an aromatic substrate stems from two considerations. First‚ there is a question of regioselectivity. Second‚ anthracene and its derivatives are highly visible under UV light. Session 2: In this lab‚ we will complete a partial conversion of 9-acetylanthracene using m-chloroperoxybenzoic acid (mCPBA). We will also determine by NMR‚ the regiochemistry of the

experiment‚ salt was extracted from the aqueous phase of known quantity butter. The following salt content determination was done by Mohr’s titration method with silver nitrate (AgNO3) in the presence of potassium chromate K2CrO4 indicator. The end-point was then spotted when the red silver chromate forms. The amount of salt in butter was obtained by calculation of the experimental result. Method 1.
