(M) of an unknown HCl solution. A NaOH solution will be made and its molarity calculated. A sample of the NaOH solution will be titrated against the unknown HCl solution to calculated the volume needed to neutralize it. With these volumes the unknown molarity can be calculated. Theory: Solutions are made up of solvents and solutes. Materials known as acids when dissolved in water produce H+ ions. Acids are the proton donators. All of the inorganic acids are aqueous solutions. A base is

POTENTIAL EFFECTS OF DISCRIMINATION. TASK 3: In looking at this task‚ we have already studied the first part of the topic at the beginning of the Unit. Forms of Discriminatory Practice exist‚ in the form of: Prejudice‚ Stereotyping‚ Labelling‚ Bullying‚ Abuse‚ Lack of choice‚ Infringement of Rights‚ and Covert/Overt abuse of Power. Do we accept that these forms of discrimination exist? What do you think……as maybe you do not agree? Discrimination can be understood as damaging the individual

The Effect of Salt Concentration on Osmosis in Potato Cells We should first explain what Osmosis is. It’s a passage of water from a region of high water concentration through membrane to a region of low water. Semi membrane is a very thin layer of material‚ which allows some things to pass through them but prevent other things from passing through. The cells allow small molecules like Oxygen‚ water‚ Carbon Dioxide‚ Ammonia. But will not allow larger molecules like Sucrose‚ Starch‚ or protein‚ etc

The rate of fermentation is faster when there is more sucrose concentration because it means there is more glucose‚ which in return means more carbon dioxide production. The sucrose concentrations were 0%‚ 1%‚ 5%‚ and 10%. The 0% sucrose concentration is just normal‚ plain water. Yeast‚ a single celled eukaryotic fungi‚ was put into the solutions. It uses fermentation to make more carbon dioxide and alcohol. In the 0% solution‚ no carbon dioxide had been produced. At the start‚ the depth of the

Part A: Title: Diffusion Diffusion is the spontaneous movement of particles from where they are more concentrated to where they are less concentrated. For this experiment‚ a 14 cm glass was filled with cold tap water. A drop of red food coloring was dropped in the cup. A stopwatch was used to measure the time it took for the food coloring to get to the bottom of the cup. The average diffusion rate was .78 cm a second. If a different color was used‚ I do not think it would have made a difference

Task 3 P3 - The potential effects of discrimination There are lots of potential effects related to discrimination. It includes things like disempowerment‚ low self-esteem and self-identity and also marginalisation. I am now going to explain these effects and connect them with a case study. Disempowerment is when a person or group of people may be made to feel less powerful or confident. Some people may try to fight against the discrimination causing an argument but many people do not and they lose

Sucrose Synthesis by D. DeWitt‚ PhD v1.5 11/10/12 Introduction | Condensation Reaction | Plant Synthesis | A. Introduction Although it might seem straight forward‚ the synthesis of sucrose‚ either as a simple condensation reaction (a.k.a. dehydration synthesis)‚ or what actually happens in plants is complicated. Before we explore sucrose’s creation‚ let’s take a look at its structure. In Figure 1‚ the space-filling model is pretty but rather useless at this point in our journey. We

Ben Zaré 9MK Biology Investigation - Osmosis in Potato Cells 9/7/04 Section 1 Planning Aim What is the aim of your experiment? What do you want to find out? The aim of this experiment is to investigate how potato tissue changes when placed in sucrose solution of different concentrations. Therefore‚ I want to find out if and how osmosis differs‚ when the concentration is changed. Variables What is the variable you are going to change in the experiment?

Water Pollution When you think of problems in the world today‚ water pollution isn’t one that would normally come up. In fact it is one of the worst problems in the world today. Water pollution‚ by definition‚ is the contamination of streams‚ lakes‚ underground water‚ bays‚ or oceans by any substances harmful to living things. All living things contain it‚ live in it‚ and most need it to survive‚ so water pollution is a big problem‚ if not the biggest. If severe‚ the pollution can kill off
