Lab Write Up Pre-Lab Questions: 1. What precipitation reaction could be used to separate and remove silver ions from a mixture containing iron (III) and zinc ions? A precipitation reaction that could be used is hydrochloric acid Ag+(aq) + HCl(aq) AgCl(s) +H+(aq) – white. 2. What precipitation reaction could be used to separate and remove iron (III) ions from the remaining mixture containing iron (III) and zinc ions? Fe3+(aq) + 3NaOH(aq) Fe(OH)3(s) + 3Na+(aq) 3. How can the presence of silver

This experiment was performed in order to analyze the effects of pH‚ enzyme concentration‚ and temperature on the catalytic rate on enzyme ALP. The initial experiment was done to approximate the optimum pH for the activity of the enzyme. The hypothesis was that alkaline phosphatase activity will be critically affected by pH effects. The hypothesis was valid because the data shows that the pH values for the acidic‚ basic‚ and neutral tubes increased over time‚ absorbing at similar rates. The basic

Production and applications Titanium and titanium alloys powders Titanium possesses an exclusive combination of low density‚ good mechanical properties at room and elevated temperatures and good corrosion resistance. Titanium and its alloys are used extensively in aerospace‚biomedical industries and in other industrial applications. However‚ titanium ingots are expensive to produce and fabricate. Another problem is connected with segregation in highly alloyed titanium materials. The high cooling

Enzymes are catalysts that speed up chemical reaction but are not themselves consumed or changed by the reaction. The cell’s biological catalysts are proteins. Proteins are made up of one or more polypeptide chains that are folded to make an active site‚ an area in which a material to be acted on by the enzyme‚ called the substrate‚ will fit. The temperature‚pH‚ the concentration of enzyme‚ and the concentration of substrate all affect the activity of the enzyme and the rate of the reaction. The

Honey powder goes by many names including granulated honey and dried honey. They all refer to honey that has been dehydrated to the point that it becomes a solid. High fructose honey tends to crystallize naturally and so it is likely that the use of honey powder has been around as long as humans have been consuming honey. Honey’s use has been documented all the way back to ancient Egypt where it was used as an important dietary supplement as well as for embalming bodies. There are cave paintings

Enzyme Lab 6 03/13/2013 Report by Mary Jo Anthony I. Introduction II. Materials and Methods III. Results IV. Conclusion and Discussion Introduction Background Information: This lab allowed us to study chemical reactions and how catalysts will affect the rate of these reactions. The reaction we studied is the breakdown of hydrogen peroxide to water and oxygen and it is vital to life. The molecule hydrogen peroxide is a molecule that is toxic

Enzyme are a very important component in living organisms. If enzymes did not exist than life itself would not exist (Lab Manual 3 pg. 1). They help in many different ways that are useful to the body of living organisms. Enzyme are used to speed up chemical reactions (Lab Manual 3 pg. 1). Through this process‚ they are considered very unique because they are not altered or consumed within the reaction (Lab Manual 3 pg. 1). This is why enzymes are considered biological catalysts. They also do not

INDUSTRY PROFILE HISTORY OF WASHING MACHINE Washing machine made their mark in the Indian market in the eighties. Videocon was the first company in India to introduce washing machine. Over the years it has remained market leader‚ with an overall market share of 35%‚ by introducing flexible strategies. Initially‚ the challenge was to ran away homemakers from their traditional method of washing clothes‚ but then‚ owing to high prices‚ the market appeared to be limited only to upper income urban

Name : Andi Nadya Amanda Period : 4 Grade : 11 Enzyme Lab Report Question How heats effect the length of reaction time of an enzyme? Hypothesis I think the heat will make the length of reaction time of an enzyme become slowly. Heat is one of a way to denature the substrate. It means the heat will break down the structure of substrate in order the reaction of enzymes that we activated into it become slowly. Method for Collecting Data First I will record the length of reaction time
