the 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

SCH 3U0 May 7th 2013 Percent Yield of Calcium Carbonate Introduction: The purpose of this experiment is to examine the percent yield of a precipitate in a double displacement reaction. A solution of calcium citrate and sodium carbonate were mixed together‚ then the products were filtered out as so only the precipitate remained. The filtered paper was then dried and the mass of the precipitate in the experiment divided by the theoretical mass of the precipitate from the calculated gave the

Rate of Decomposition of Calcium Carbonate Theory Calcium carbonate‚ CaCO3‚is one of the most abundant minerals on the Earth. More than 4% of the Earth’s crust is composed of calcium carbonate. It is a major component in limestone‚ marble‚ seashells‚ bedrock‚ etc. Limestone and marble have been among the most widely used building materials for more than 5 000 years‚ from the pyramids in Egypt to the Parthenon in Greece and the Taj Mahal in India. In many places‚ limestone is also the foundation

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

Vitamin c in fruit juice using dcpip titration Preparing the standard ascorbic acid solution 1. Weigh out accurately about 0.2 g ascorbic acid and make up to 1 L with distilled water. 2. Calculate the concentration of the ascorbic acid solution: C = n/V = m/M/V. Sample calculation: mass of ascorbic acid = 0.205 g C (ascorbic acid) = 0.205/176.12/1.00 = 0.00116 M Preparing the DCPIP solution Weigh out accurately approximately 0.24 g DCPIP (Mr = 268.1g/mol) and make up to 1 L with

determine energy lost by Calcium Chloride and gained by Ammonium Nitrate when dissolved in Water. Theory: Exothermic reactions are when net energy is lost in process of reaction. When solid calcium chloride (chemical formula CaCl₂) is placed in water‚ the calcium chloride dissolves and liberates heat in the process. Calcium chloride is one of the ingredients in instant "hot packs" sold in retail stores. Some concrete mixes incorporate calcium chloride to decrease drying time. Calcium chloride is also used

Vitamin C Molecule Investigation Thomas Philpott Introduction Vitamin C (ascorbic acid) is an essential component of human nutrition‚ as it is an antioxidant that the body requires. Having a deficiency in Vitamin C can lead to scurvy‚ a disease characterized by abnormalities in human bones and teeth. Fruits and vegetables are common sources of Vitamin C‚ notably oranges and citrus fruits. Cooking and the application of heat destroy the vitamin so such fruits must be raw in order to obtain the

much of a good thing is an adage that can apply to vitamins. The body needs vitamins to function properly‚ but high doses of certain vitamins can be toxic‚ especially fat soluble vitamins that the body stores for long periods of time. Water Soluble Vitamins Water-soluble vitamin toxicity is rare because the body does not store water-soluble vitamins and excess amounts are usually excreted in urine. Side effects associated with water-soluble vitamins occur due to intake of extremely high doses. Peripheral
