Concentration of a Potato Aim: In this investigation I am going to work out the sugar concentration of a potato. I aim to find this out by putting potato cores into various concentrations‚ measuring the mass before and after. Due to osmosis the potato cores will change in mass to make the concentrations at an isotonic level‚ helping us to work out the mass of the potato. I predict that potato in the weaker solutions will gain mass‚ because some water will be absorbed by the potato to make the concentrations

Marble Chip Investigation Method 1.Set up the equipment as diagram shows. The measuring cylinder must be filled with water and then inverted into the tub. 2.Measure the quantity of hydrochloric acid and marble chips to the decided amount. Add water to the acid to change the concentration to what you need. 3.Take note of the amount of water in the measuring cylinder. 4.Put the marble chips and hydrochloric acid into the conical flask. Replace the bung and start the stopwatch. 5.Once the decided

Why do entrepreneurs start a business? Mainly‚ to make a profit and the South African company Simba‚ which produces a convenient snack‚ crispy chips‚ has so far done just that. They have become a booming business‚ expanding on their range of flavors for their chips. They have teamed up with Pepsi‚ and converted their food only company to a food and beverage supplier to many outlets throughout South Africa. Simba has become such a popular and well-known brand because the eight different functions

do: We will put potato pieces of similar sizes in to test tubes of different concentrations of sucrose solution‚ and measure any changes in mass and length. Affecting Factors: There are a number of factors which can affect our results. We need to keep them all the same‚ and make sure that the only thing that changes is the concentration of the sucrose solution. These factors include: • Starting length of potato • Volume of Sucrose solution • Temperature of potato • Temperature

Investigating the rate of reaction between Marble Chips (Calcium Carbonate) and hydrochloric acid Aim. In the investigation I am going to find out how the surface area affects the rate of reaction by measuring the amount of gas produced and weight loss in a reaction between small/large pieces of Marble Chips (Calcium Carbonate) and Hydrochloric acid per minute. Hypothesis. The rate of reaction increases when the surface area of a solid reactant is increased. This happens because by

investigate about enzymes in potatoes reacting with Hydrogen Peroxide. In particular I will investigate the effects of changing the surface area of a potato when added to Hydrogen Peroxide. This is because‚ when increasing the surface area of the potatoes it will increase the rate of reaction because there will be more surface area on which particles from the potato and the Hydrogen Peroxide will collide on‚ and with more surface area there would be more particles carrying kinetic energy‚ and by carrying

Experiment to Investigate Osmosis in Potatoes The aim of this experiment is to investigate the movement of water in and out of plant cells. The cells chosen for study will be taken from potato tubers. Firstly I will explain what osmosis is. Osmosis is the passage of water from a region of high water concentration through a semi permeable membrane to a region of low water concentration. This definition contains three important statements: a) It is the passage of water through a semi permeable membrane

Solution for Chapter 2 Exercise 5a 5. a. Draw the hierarchy chart and then plan the logic for a program for the sales manager of The Couch Potato Furniture Company. The manager needs a program to determine the profit on any item sold. Input includes the wholesale price and retail price for an item. The output is the item’s profit‚ which is the retail price minus the wholesale price. Use three modules. The main program declares global variables and calls housekeeping‚ detail‚ and end-of-job
