    What are eggshells made of? The main ingredient in eggshells is calcium carbonate (the same brittle white stuff that chalk‚ limestone‚ cave stalactites‚ sea shells‚ coral‚ and pearls are made of). The shell itself is about 95% CaCO3 (which is also the main ingredient in sea shells). The remaining 5% includes calcium phosphate and magnesium carbonate and soluble and insoluble proteins.

    PLANNING AND GATHERING INFORMATION PURPOSE: The purpose of this project is to determine whether different brands of caged or free-range hen eggs have stronger shells. This project will prove whether caged or free-range hen eggshells are stronger. HYPOTHESIS: My hypothesis for this project is that free-range hen eggshells‚ in all of different brands are stronger than caged hen eggshells. I choose free-range eggshells‚ because their diet and lifestyle would be different from caged eggs. EQUIPMENT:

    eggshell experiment

    Introduction The major component of eggshells is calcium carbonate (CaCO3). Calcium carbonate cannot be dissolved in water‚ but can dissolve in an acid using the reaction: 2HCl(aq)+CaCO3(s) Ca2+(aq)+CO2(g)+H2O+2HCl-(aq) This reaction is not used to titrate the CaCO3 because it is very slow when the reaction is close to the endpoint. Instead adding an excess of acid to dissolve all of the CaCO3 and then titrating the remaining H3O+ with NaOH solution can achieve the determination of the amount

    which the commercial one could give through eggshells. This steps was made by the researcher to make a chalk out of eggshells;First she clean the empty eggshell of the chicken through washing‚then when the eggshells is already dry‚ she pound the clean eggshells very well until it will become a powder‚then she get the residue and she separate it from the eggshell that is already in powder then she pour a liitle amount of water into the powdered eggshell and put it on the paper to form a stick chalk

    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

    energy will be attainable. Hypothesis: In a reaction between calcium carbonate and hydrochloric acid‚ the products calcium chloride‚ carbon dioxide and water are formed. I predict that the higher temperature of HCl acid‚ the higher the reaction rate will be‚ this is because at a higher temperature there will more fast-moving hydrochloric acid molecules per set volume. This means that there will be a higher chance of the calcium carbonate molecules colliding with the hydrochloric acid and reacting

    Introduction In order to determine the content of calcium and magnesium in an unknown sample of limestone‚ the utilization of atomic absorption spectrophotometry can help in deciphering the unknown concentrations of each molecule in the limestone sample. Atomic absorption spectrophotometry‚ emits radiation of the correct frequency that is passed through a flame and the intensity of the transmitted radiation is measured¹.The calcium concentration or ppm can be measured using the absorbance of the
