I am going to investigate osmosis when potato is placed in different concentrations of sucrose. I am aiming to witness osmosis in 5 different concentrations of sucrose. I will use 5 varying concentrations so that I have a wider spread to compare the results‚ and check that I don’t have any anomalies Prediction Osmosis is the process of diffusion of water molecules from a weaker solution into a stronger solution‚ through a semi permeable membrane. The tiny pores in the membrane

supernatant liquid and denser slurry having a higher concentration of solids. This is usually accomplished by allowing the particles to settle through the force of gravity‚ mechanically using centrifugal force‚ or electrostatically using an electric current. Continuous sedimentation tanks are usually used in wastewater treatment facilities to separate suspended particles from wastewater. This experiment aims to determine the effect of initial concentration and initial height of the slurry on its settling

Rate of Decomposition of Calcium Carbonate Theory Calcium carbonate‚ CaCO3‚is one of the most abundant minerals on the Earth. More than 4% of the Earth’s crust is composed of calcium carbonate. It is a major component in limestone‚ marble‚ seashells‚ bedrock‚ etc. Limestone and marble have been among the most widely used building materials for more than 5 000 years‚ from the pyramids in Egypt to the Parthenon in Greece and the Taj Mahal in India. In many places‚ limestone is also the foundation

Criminal Investigations In criminal investigations there are many aspects throughout the field that are very interesting. Some aspects are crime scene investigation‚ getting witnesses‚ taking and handling of evidence‚ investigative sources‚ legal aspects‚ interview and interrogating and case management. My favorite aspect of criminal investigating is taking and handing of the evidence and interviewing and interrogating. Today new and improved tools and techniques in the criminal investigation process

I think we can all say that we’ve stayed up later than we’d planned to on our phones‚ TVs‚ iPads etc. before and didn’t have a good sleep because of it. It may not seem like such a big deal to get a little screen time in before bed‚ until you realize just how much exposure you get to it everyday. Technology affects your sleep in a lot of negative ways. It disrupts your sleeping patterns‚ keeps your brain alert‚ and wakes you up. Melatonin is a natural hormone made in your body’s pineal gland‚ and

Abstract This investigation was undertaken in order to observe the effects of changing the temperature of the solution that a potato cube is placed in. The temperatures that were tested in this investigation were 0°C‚ 20°C (room temperature)‚ and 70°C. This investigation tested the hypothesis: The rate of osmosis will increase as the temperature increases 2x2x2cm cubes of potato were weighed and then placed into 100mL of 10% NaCl solutions for 10 minutes. After 10 minutes the cubes were again

Often two types of investigations have been differentiated. The ‘reactive approach’ to investigation occurs when a police responds to a crime that has already taken place such as murder‚ or theft. On the other hand‚ the ‘proactive approach’ to investigation occurs in response to an ongoing criminal activity or even before the crime has been committed. For e.g. the police may get information that a gang is going to commit a crime in a particular area. In other cases‚ the police may patrol an area

Investigating the effects of changing concentration: iodine clock reaction. Abstract This is an experiment to show the Iodine Clock Reaction. To create a chemical reaction to see how long it takes for solution to change to a dark blue Color. When changing the concentration of the iodide (K1) and adding distill water to make it up to 5cm³ each time. This is to see if the reaction takes less with less concentration or faster with more concentration added to the peroxodisulphatee. So with the solution
