Page 153 to 158 (Experiment Title: “Determination of Mg+ using a Complexmetric Titration”) Introduction: In this experiment‚ EDTA (ethylenediaminetetraacetic acid) is use as a controlled chemical to determine the concentration of Mg2+. The reason why EDTA is used is because EDTA reaction has large equilibrium constants‚ so it is easy to measure. In basic solution‚ EDTA loses 4 protons to become the conjugate base commonly

insect feeding‚ essentially acting as natural pesticides. There is evidence that suggests that methylxanthines could be among these substances. A study was performed‚ using tobacco hornworm larvae‚ to see if there were pertistatic and pesticidal effects of caffeine. Powdered coffee beans‚ combined with a liquid‚ were placed in petri dishes in concentrations ranging from 0.3 to ten percent. Instar larvae were placed in the petri dishes and showed symptoms such as hyperactivity‚ stunted growth and

How Enzyme Concentration can Affect Rate of Reaction The purpose of this investigation was to see how the concentration of an enzyme affected the rate at which a substance was broken down. We did this by using a white protein called casein. Casein is found in milk powder‚ it is a protein and used mainly as a binding agent in foods‚ because it is mad to proteins and joins to a phosphoric acid it belong to a group called the phophoproteins. In terms of in milk it is said to be healthier if it is

Investigation Into Temperature Sensors Introduction In this project I will be investigating how it is possible to use a temperature sensor to keep a greenhouse from changing temperature too much. This is intended to help plants live and grow in their optimum temperature. This will create a perfect temperature for the enzymes in the plants to work in‚ and therefore resulting in a maximum growth/production rate. This could be useful for gardeners who wish to grow plants as quickly as possible

PUTTING IT TOGETHER: Classifying Chemical Reactions Purpose: To observe and differentiate between the four different types of chemical reactions. Variables: The independent variables are the sodium chloride‚ sodium carbonate‚ magnesium‚copper‚ copper (11) sulfate‚ silver nitrate‚ oxygen‚ lead(11) nitrate‚ sodium carbonate‚ copper (11) sulfate pentahydrate. The dependent variables are the chemical reactions that are being looked for. For example decomposition‚ synthesis‚ single displacement or double

of alertness (a CNS effect) but also a higher heart rate‚ blood pressure and respiratory rate. Caffeine also acts as a stimulant drug‚ causing increased amounts of stimulatory neurotransmitters to be released. At high levels of consumption caffeine has been linked to restlessness‚ insomnia and anxiety‚ causing raised stress and blood pressure. This can lead to heart and circulation problems. Hypothesis: Daphnia subjected to a caffeine solution will show a rise in heart rate as caffeine is a stimulant
