The purpose of the experiment is to determine the effect of cross-linking has on the viscosity of the polymer solution. In the experiment‚ a hotplate was used to heat 50 mL of tap water in a 200 mL beaker to boiling. It took nearly two hours to fully dissolve 2 grams of PVA [poly(vinyl alcohol)] in the water by sprinkling minor amounts bit by bit. 10 drops of 0.1% methyl red indicator was added to PVA solution for the cross-linking part. 0.4 grams of borax was dissolved into 10 mL of hot water. 3

Lab 2 Report for MATSE 473 Determining Molecular Weight using Solution Viscosity Name: Mengfang Li Group D Lab Partners: Michael Lorenzo‚ Peter Mcclure 01/24/2012 Introduction: This lab was designed to demonstrate the method to measure the intrinsic viscosity of the prepared polystyrene. Intrinsic viscosity‚ which is measured from the flow time of a solution through a simple glass capillary‚ has considerable historical importance for establishing the very existence of polymer molecules

Anyone on a clear liquid diet is doing that due to medical procedures such as surgery‚ having the flu‚ or sometimes other stomach disorders until they can go on solids again. The clear liquid diet is only that: foods that will go down easily and don’t require a lot of digesting. The clear liquid diet helps the person on it to stay hydrated enough for the body to function‚ and also provides you with electrolytes that are needed as well. This type of a diet is usually for the shorter term until whatever

Determination of Cleansing Action of Detergents (Using Capillary rise) Synopsis This project report explains about the surface tension and capillarity of liquid through a simple experiment of finding the capillarity of various detergents. Oil stains and grease on dirty clothes cannot be removed‚ using water alone‚ because water does not wet them. If detergents added ‚ surface tension is decreased‚ the area of contact is increased

Do all liquids evaporate? What would happen if liquids never evaporated? Do we know which liquid evaporates the fastest? Could we perhaps use this knowledge to change the everyday processes? The process of evaporation happens much differently than scientists once thought. Every liquid eventually evaporates and often what remains is the solid particles which were once part of the solution. Evaporation is very important: “it shapes the climate of the planet‚ it affects the cost of car travel

DISTILLATION ABSTRACT Distillation‚ one of the most significant method for separating a liquid mixture and its components‚ is a process that relies on differences by the ease of vaporization of the components. The purpose of this process is either the separation of a mixture of volatile components from nonvolatile materials is carried out by a simple distillation in which the material is placed to distill and heated‚ the vapor from the substance is removed and condensed. In this activity

Over the last decade‚ drinks containing high amounts of caffeine‚ sugar‚ and other ingredients that increase energy have been rapidly growing in popularity. Clearly these beverages are known as energy drinks. Energy drinks have gotten so popular that it is extremely rare to find a convenience store that doesn’t sell a variety of them. Students use energy drinks to cram the night before a test‚ athletes use them
