Aim: To investigate the rate of reaction between Calcium Carbonate and Hydrochloric Acid. Just from looking at the aim of the investigation I already know that a salt would be formed because a carbonate with an acid forms a salt. In this investigation the substance that is formed is Calcium Chloride‚ Water and Carbon Dioxide. The symbol equation for this is: CaCo3  Ca2+ + Co32- Hcl  H+ + Cl- Add these all together to get CaCO3(s) + 2H+(aq) --> Ca++(aq) + H2O + CO2(g) The rate of

Marble Chips And Hydrochloric Acid Planning I will use marble chips and different concentrations of hydrochloric acid and water to see how it affects the rate of reaction. I will use concentrations of 50cm3 using different volumes of water and acid. Introduction I am investigating how the rate of reaction between marble chips and hydrochloric acid is altered when the concentration is changed. This is the word equation for my investigation‚ Calcium + Hydrochloric Calcium + Carbon

Action of Saliva and 3 M Hydrochloric Acid in Two Carbohydrate Solutions Lecturer’s name: Mr. Paul Davidson Discussion The name of enzyme involved in this experiment is salivary amylase‚ which presents in our saliva. Salivary amylase catalyses the breakdown of complex sugar‚ such as starch‚ into a simple sugar‚ such as glucose. In this experiment‚ the optimum temperature for salivary amylase to function is 37˚C. Above the optimum temperature‚ the kinetic energy

Solubility of Calcium Hydroxide Apparatus * Solid calcium hydroxide * 0.4 mol/dm hydrochloric acid * Distilled water * Pipette * Triple valve rubber pipette filler * Conical flask * Beaker * White tile * Clamp and stand * Methyl orange indicator Producing the calcium hydroxide solution 1. Roughly fill a beaker with 200cm³ of distilled water. This does not need to be accurate because samples will be taken from this. 2. Add solid calcium hydroxide‚ a spatula at a

To investigate how does the concentration of Hydrochloric acid affect the rate of reaction? Outline I aim to discover how different concentrations of Hydrochloric acid influence the rates of reaction. In order to carry out this investigation I have decided to use marble chips‚ which I will vary the sizes as powder‚ small chips and large chips. I will also be changing the concentration‚ the different concentrations are as follows 0.2m‚ 0.5m‚ 1m‚ 1.5‚ 2m. I have chosen these concentrations as they

Analysis of Soda Ash and Volumetric Analysis of a Carbonate-Bicarbonate Mixture Buti‚ Mary Daphne A. Department of Chemical Engineering‚ Faculty of Engineering University of Santo Tomas España‚ Manila Abstract Sodium carbonate (Na2CO3)‚ commonly known by trade name soda ash‚ is a white‚ anhydrous‚ powdered or granular material that is an essential raw material used in the manufacturing of glass‚ detergents‚ chemicals‚ and other industrial products. In this experiment‚ the percent alkalinity

between sodium thiosulphate (thio) and hydrochloric acid. Hydrochloric Acid + Sodium Thiosulphate "" sodium chloride + water + sulphur The reactants are both colourless‚ but one of the products‚ sulphur‚ is yellow‚ so we can use this fact to follow the rates of reaction. I am going to investigate how the concentration of the acid effects the speed of the reaction.

Heat‚ Temperature‚ and Phase Changes Assessment Practice Answer This graph shows what happens to the temperature of the water‚ while it was boiling in a kettle‚ as heat energy was being added to it and what the water was doing will it began to warm and change states. During a phase change‚ the temperature remains mainly constant. This occurs because the heat energy is used to break the bonds between the ice molecules as they turn into a liquid phase. It is possible to constantly

Sodium: Sodium is essential to all living beings Basic functions: Sodium has 3 main functions: it helps in the absorption of glucose and some amino acids in the small intestine‚ it is required for normal muscle and nerve function‚ and it aids in water balance. Glucose generated by digestion of starch or lactose is absorbed in the small intestine only by cotransport with sodium‚ a fact that has exceptionally important implications in medicine. Glucose and galactose are taken into the enterocyte by
