to determine the solubility constant of calcium hydroxide. But‚ there are few limitations in solubility constant concept‚ like the Diverse Ion effect and the Common ion effect. Sources of error probably were the assumptions made throughout the experiment and can be explained further by the limitations of the solubility constant. ------------------------------------------------- ------------------------------------------------- Introduction In a reaction where a slightly soluble ionic solid

Biotechnology‚ Mapua Institute of Technology ABSTRACT In this experiment‚ solubility class of various organic compounds are to be determined. The main objective of the experiment is to identify an unknown compound through the use of preliminary tests such as examination of physical state‚ color‚ odor‚ and ignition properties. Also‚ solubility tests were used to further examine an unknown compound’s solubility class. In this experiment‚ the apparatus used are micro test tubes and droppers for mixing

The Bobo Experiment was performed in 1961 by Albert Bandura to try and prove that people‚ especially children‚ learn their social skills and behaviors from copying or mimicking adults in their lives rather than through heredity genes. Bandura wanted to show‚ by using aggressive and non-aggressive adult-actors‚ that a child would be apt to replicate and learn from the behavior of a trusted adult (Shuttleworth‚ M. 2008). These issues have been present for many years‚ even before the media used these

Abstract Over a two week period of time in the laboratory‚ we experimented and tested the reaction rate of a peroxidase enzyme and the factors that affected it‚ both positively and negatively. The purpose of these experiments was to probe and manipulate the activity of the enzyme peroxidase by varying temperature‚ pH‚ the amount of enzyme compared to the substrate and the effect of hydroxylamine. Peroxidase activity is expressed when the potato extract is subjected to stresses such as low temperature

were derived from his experiments‚ proved that obedience is one of the basic elements in the structure of social life. The proximately of the victim‚ responsibility for the actions‚ and perceived legitimate authority figures will greatly determine how far an individual will go to fully comply. Obedience‚ which is one of many social influences in our life’s‚ results in a change in behavior when a direct command is given by a high authority. The main focus in Milgram’s experiment was to specify what

Salt from green beans Name: Ashni Couprie and Dennise Susanto Class: 5c Introduction From previous experiments we ’ve learned that salt is extracted from green beans. To be more specific: salt is extracted from when the beans are cooked in water in which salt has been dissolved. This experiment is based upon the osmoses theory. According to this theory the cell walls of the green beans are what we call a semi permeable membrane. This membrane only lets water through and not the substance

EXPERIMENT 7: PERCENTAGE OF OXYGEN IN KClO3 Introduction: In this experiment you will determine the percentage of oxygen in potassium chlorate. You will calculate the theoretical value from the chemical formula and compare your experimental value to the theoretical value. Background: When potassium chlorate (KClO3) is heated‚ it undergoes chemical decomposition. Oxygen gas (O2) is given off and potassium chloride (KCl) remains as the residue. The equation for the decomposition of potassium

The effect of varying temperature on thee Rennin enzyme Abstract The purpose of this experiment was to see what affect different temperate had on the reaction rate of the enzyme rennin. The experiment was performed by placing test tubes filled with renin and milk into water bath which was heated or cooled to one of the temperatures trialed. The hypothesis justified because it found because it though data that the enzyme reacted faster with the 45° temperate because it was
