Determination of KHP – Acid - Base Titration For determining purity of unknown KHP‚ acid – base titration was used. Molarity of titrant in this case NaOH was standardized as 0.04958(±0.00011) M. Purity of unknown KHP was calculated as 35.88(±0.16) %. • Introduction Acid – base titration is typical method of determining unknown figures. Acid – base titration means that by using neutralization between acid and base. Abrupt changing of pH says whether procedure is done or not. pH indicators

Determination has helped many well known brands and people become known . One of the most important keys to success is determination. There are many details‚ and aspects from texts‚ but there were three reasons that were evidenced from the articles The business of beanbags‚ Climbing Kilimanjaro‚ and The Mighty Macs that stood out. The first reason is that being motivated can benefit you in many ways. Motivation is a reason to do something‚ or take action. By being motivated‚ Lilian Wairimu Njue

Lab #2 Determination of Density Britney Williams Chemistry 121 Dr. Yu 1/29/13 Purpose: To determine the densities of aluminum and zinc cylinders Density is the relationship between the mass of an object and its volume. Sometimes density can be easy to sense. If two objects have exactly the same shape and size‚ the denser one may feel heavier. If their densities are close together‚ it can be hard to tell the difference. It gets really tough if you are dealing with materials that have very different

Tittle: Determination of moisture Objectives: 1. To determine the moisture content of selected food samples using drying oven method 2. To determine the moisture content of selected food samples using moisture analyzer. Introduction: Moisture content is one of the most commonly measured properties of food materials. The choice of an analytical procedure for a particular application depends on the nature of the food being analyzed and the reason the information is needed. In this experiment

The micro-hardness test can measure the case to core depth parts. Micro-hardness testing is required where the superficial hardness test is not conceivable due to material’s small geometrical shape. The welded part we were going to examine‚ experienced the similar criteria since the welded bead of the joint was way too small. To test the hardness of our welded area we had gone through a micro-hardness test using a Shimadzu micro-vicker hardness testing machine. In the following
