Ground calcium carbonate‚ commonly referred to as GCC‚ is primarily based on limestone and chalk in the UK‚ though marble stone is imported and processed at a few locations. Generally‚ the processing includes washing‚ sorting of undesirable contaminants‚ grinding‚ size classification of particles and possibly drying. http://www.crusherindustry.com/index.php/ground-carbonate-calcium-factory-for-sale-uk/ T130x ultrafine grinding mill is a fine powder and ultrafine calcium carbonates powder production

Zinc and Hydrochloric-Acid Written By Kahlil Zione Date:02/02/05 Abstract: We observed the reaction between zinc and hydrochloric acid and recorded it in a table and learned wether the percentage of zinc is effected by the amounts of both substances added to the solution. Introduction The purpose of this experiment is to determine if the amount of zinc and hydrochloric acid will effect the percentage of the zinc in the out coming solution. We are reacting zinc metal with hydrochloric

Antacids are defined as a substance‚ generally a base‚ which counteracts stomach acidity. The name antacid means anti-acid (against acid). Antacids are the primary treatment for ailments such as gastric reflux‚ gastritis‚ upset stomach and heartburn. Hydrochloric acid is secreted by the stomach to kill harmful organisms‚ aid digestion and activate digestive enzymes. Excess secretion of acid into stomach or impaired resistance by the lining of the stomach or reflux into the oesophagus may produce symptoms

mass of Calcium carbonate in an egg shell Aim: is to find and work out the percentage of calcium carbonate by mass in eggshells by using acid base “back titration” Introduction: Calcium Carbonate‚ CaCO₃‚ is a compound which is polymorphic and therefore means that it can be found in a variety of different objects or organisms. For example: Rocks (limestone‚calcite)‚ sea snail shells‚ Eggshells‚ pearls and many more. This investigation will focus on finding out the percentage mass of calcium carbonate

purpose of this experiment is to determine the percentage by mass of calcium carbonate in eggshells. Introduction To avoid the breakage of eggs before reaching market‚ the eggshells needs to be as strong as possible. The strength of eggshells is mainly determined by the percentage of calcium carbonate in it. In order to monitor the quality of eggshells‚ the following experiment has to be done to determine the percentage of calcium carbonate in eggshells. In this experiment‚ back titration is

Neutralization experiment AIM:- To investigate how heat is given out in neutralizing sodium hydroxide (NaOH) using different concentrations of Hydrochloric Acid. Background Information:- Substances that neutralize acids are called alkalis. An acid is a substance that forms hydrogen ions (H+ ) when placed in water. It can also be described as a proton donor as it provides H+ ions. An example of an acid is hydrochloric acid (HCl)‚ Sulphuric acid (H2SO4) etc. An alkali is a

AIM: To carry out a lab experiment to decompose a carbonate using heat‚ also to carry out appropriate tests for the formation of products as a result of this decomposition. DISSCUSION: Carbonates are decomposed by heat into the corresponding oxides and carbon dioxide. The temperature of decomposition depends upon the activity of the metal; that is to say‚ the more active the metal‚ the more stable is the carbonate. Thus‚ the carbonates of sodium and potassium are stable at the highest temperature

substances are required for Calcium carbonate precipitation Abstract: Introduction: Different minerals precipitation by microbes is a common phenomenon‚ and carbonates are most common mineral formed. Many micro-organisms are having the ability in undergoing the process of mineralization‚ although different minerals have been precipitated by microbes which include carbonates‚ sulphates‚ silicates etc [1]. Amongst all these‚ carbonates are the most common minerals formed. Carbonate precipitation has been
