    pollution that makes our Environment damage so we decided to make funky colored sidewalk egg chalk as our science investigatory project. So based on our title name we will use eggshell not any eggshell because we will use chicken eggshell as an alternative ingredient for sidewalk chalk‚ we believe that this study will be great and popular because as of now children‚ students and teachers consume many of chalk which is expensive so we do this study and improve it for children who plays on sidewalk outside

    The Importance of Calcium Ions Alyssa Foels 12 February 2015 Kilfe Calcium is a cation‚ a positively charged atom‚ and it is essential to all living things. It was first discovered in 1808 by Humphrey Davy. When forming an ionic bond with other elements‚ calcium loses electrons to make its valence shell stable. This means that it has more protons than electrons‚ making it have a slight positive charge (Calcium). Calcium has many roles and functions in the human body. Calcium ions are the most

    In this experiment‚ gravimetric analysis will be used to determine the unknown metal carbonate. Gravimetric analysis. Gravimetric analysis is a method where an ion being analyzed can be classified through their mass (Yoder 2018). Due to the fact that carbonates can be hygroscopic‚ which means it would be able to absorb water from water vapor‚ extra precautions have to be taken place to be able to get an accurate mass (Helmenstine 2017). This can be done by using a drying oven and a desiccator. A

    Calcium is an extremely important factor for health and longevity. It serves both a structural and physiological role in the entire organism. Bones are constantly breaking down and rebuilding‚ and calcium is directly involved in this process. Calcium ions (Ca2+) are essential mediators of a wide variety of cellular activities‚ including the passing of information along neurons and between adjacent neurons. Hormonal regulation is also mediated by the proper functions of calcium and calcium ions

    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 of acid‚ which has not reacted
