How did the amount of Sodium Citrate‚ an anticoagulant‚ added to a Calcium Chloride solution affect the volume of the clots formed when a sodium alginate solution‚ a blood simulation‚ was introduced? Mackenzie Keesor (Fall Semester 2017-2018) Purpose The purpose of this experiment was to observe the differences in the formation of simulated blood clots when different amounts of sodium citrate‚ an anticoagulant‚ was added to the coagulation process‚ which would help gain information about the process

Shivandu Patel‚ Dilan Kapadia Standardizing a Solution of Potassium Hydroxide Abstract: In this lab‚ a prepared solution of Potassium Hydroxide will be standardized. The solution we will be standardized by performing multiple calculations to ensure the upmost accuracy. The acid used for this titration will be KHP (C4H5KO4). Phenolphthalein we be added to the beaker of the dissolved acid before the titration will be added. The titration will stop when the solution turns pink and the color doesn’t go

A titration is a method where a solution of known concentration is used to determine the concentration of an unknown solution. Typically‚ the known solution is added from a burette to a known amount of the unknown solution until the reaction is complete. Knowing the volume of the known solution added allows the determination of the concentration of the unknown. Often‚ an indicator is used to usually signal the end of the reaction‚ the endpoint. Concentration is the abundance of a constituent divided

in acid-base titrations Objectives 1. To understand the importance of choosing suitable indicators for detecting the end points of acid-base titrations. 2. To obtain titration curves for some acid-base titrations. Introduction Indicator is usually a weak organic acid or base that has distinctly different colours in its protonated and deprotonated forms. There are 4 types of acid-base titrations such as strong acid-weak base titration‚ weak acid-strong base titration‚ strong acid-strong

Sodium chloride‚ also known as salt‚ common salt‚ table salt‚ or halite‚ is an ionic compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. [edit] Properties Thermal conductivity of pure NaCl as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K and decreases to 0.069 at 314
