11/29/2012 Lab # 11 – Acid - Base Titration Introduction: The purpose of this lab is to determine the molarity (M) of an unknown HCl solution. A NaOH solution will be made and its molarity calculated. A sample of the NaOH solution will be titrated against the unknown HCl solution to calculated the volume needed to neutralize it. With these volumes the unknown molarity can be calculated. Theory: Solutions are made up of solvents and solutes. Materials known as acids when

Title Page Density Formal Lab Report Name Professors Name Date Purpose/Objective: Determine density of a product for a plastic manufacturing facility. Provide quality control by making sure the physical properties are within design specifications. Density is defined as the ratio of an object’s mass to its volume‚ measured by dividing mass by volume (density = mass/volume). This was accomplished using two different experimental methods‚ displacement and floatation. The theory is that

the maiden voyage of the Titanic was a symbol of the advances mankind had made in the last few years. The ship was considered to have been so well constructed it was believed she could sustain any amount of damage and still remain afloat. Late on the night of April 14‚ 1912‚ the sinking of the Titanic proved this idea wrong in a horribly tragic way. The causes of Titanic to sink have been the subject of much study and debate. Obviously‚ the instigating factor was the collision with the iceberg;
