concentration of CaCO3 obtained was 1034 ppm‚ with a standard deviation of 2.4495. The results indicate that the unknown solution can be considered as hard water. Introduction The hardness of water is defined in terms of its cation content‚ which includes calcium‚ magnesium‚ iron‚ zinc‚ and other polyvalent metal ions. These metal ions interfere with the use of the water for many applications. For example‚ these ions diminish the effectiveness of soap and detergent for cleansing operations; they diminish

chemical plants. Screw conveyor is also one important part in concrete batching plant. Screw conveyor is mainly used for conveying powdery‚ granular and small blocky materials‚ such as coal dust‚ soda ash‚ recycled rubber powder‚ zinc oxide‚ calcium carbonate and small pieces of coal. Screw conveyor is not suitable for conveying perishable and viscous materials and materials which is easy to blocking. Spiral blades welded on the rotation axis of screw conveyor have different types according to

Chemistry Lab Report Stoichiometry Design Experiment Percentage Yield of Calcium Carbonate and HCl I. Background Information When marble chips and hydrochloric acid are added together‚ they form sodium chloride‚ water‚ and carbon dioxide. This reaction can be displayed by the balanced equation below; CaCO3 (s) + HCl (l) NaCl(s) + H2O(l) + CO2 (g) As the carbon dioxide is formed‚ it will leave the open beaker as a gas. This will result in a loss of mass. The mass change can then be

:ABSTRACT The researcher conduct this study due to economics crisis nowadays. It’s aim to create a product of chalkwhich is cheaper and could give the same quality 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

Determination of Water Hardness Using a Titrator Heather Crall Chemistry 1 SMT- 271044 10/17/2012 Abstract From seeing all of my results and conclusion I now see that I didn’t understand this lab very well and that its not easy when others try to help. Since I have hard water it tells me that my water flows over and through rocks and minerals‚ like limestone. Purpose The purpose of this lab is to become familiar with the concept of water hardness. We learn that hard water contains
