Effect of Temperature on Solubility Lab Purpose: What is the solubility of minerals in water? What is the relationship between temperature and solubility? Hypothesis: If salt and sugar are each tested in water of varying temperatures‚ then salt and sugar’s solubility will increase as the temperature also increases. Materials: Two 250 mL beakers Tap water 100 mL graduated cylinder Hot plate Two petri dishes Glass stirring rod Salt Sugar Thermometer

THE GRAVIMETRIC DETERMINATION OF SULFATE Learning Goals. 1. To determine the amount of Sulfate in an Unknown sulphate sample. 2. To perform and develop skills in precipitation Gravimetric method of quantitative analysis. DISCUSSION: Gravimetric analysis is one of the oldest analytical techniques and for this reason is referred to as a "classical method." Gravimetric procedures are usually very accurate‚ but more tedious than other methods. The only major equipment needed

Calugay______ An experiment to obtain and compare the spring constants of 3 strings (soft‚ medium‚ and hard) obtained in 2 ways (using the energy chapter and the dynamics chapter)‚ to confirm that Hooke’s Law is valid over a range of initial displacements‚ and to find the acceleration due to gravity on unknown Planet X. Problem: What are the spring constants of 3 strings (soft‚ medium‚ and hard) and how do they compare? Theory: To find the spring constants of each string‚ we can calculate the velocity that

When estimating the effect of changes in the money supply to changes in nominal GDP‚ it is common to assume that the velocity of money is constant. The velocity of money is a measure of average number of times per year that a dollar is exchanged. The quantity theory of money states that the money supply multiplied by the velocity of money is equal to the price level multiplied by output. ( ) Price level multiplied by output is the nominal output. Therefore‚ a percent change in the money

FRS 15 ‘Tangible fixed assets‘ FRS 15 was issued in February 1999 and sets out the principles of accounting for tangible fixed assets‚ with the exception of investment properties. The objective of the FRS is to ensure that tangible fixed assets are accounted for on a consistent basis. Fixed assets are held in our company for the profit of their use not from their resale. Tangible fixed assets should be capitalized when they are ready for use‚ which means when its physical completion is complete

Standardisation of a Solution of Sodium Hydroxide: Introduction: In a lot of cases it isn’t possible to prepare a solution by accurate weighing of the solute‚ dissolving in water and diluting to volume. There are many possible reasons for this‚ but in the case of sodium hydroxide‚ the solid absorbs moisture from the air‚ and also reacts with carbon dioxide from the air. In that case‚ it cannot be accurately weighed in air. In an experiment like this‚ a solution of the approximate required concentration

Bilirubin is a breakdown end product of heme containing proteins. About 80% of bilirubin is formed from the degradation of erythrocyte hemoglobin after 120 days of erythrocyte life in the blood. The remaining 20% of daily-produced bilirubin is formed from erythrocyte precursors in bone marrow and other heme proteins: myoglobin‚ cytochromes‚ and catalase. Hemoglobin degradation begins with opening of the heme porphyrin ring‚ forming the biliverdin – iron – globin compound known as verdoglobin.
