how to measure carbonate in an ore sample gcse carbonate ore and hcl reaction Grinding Mill China 2013326- This method describes how to ascertain the relative proportion of carbonate in an ore sample based on the duration of a reaction with HCl. How can I quantify the presence of carbonate and,
Sodium hydrogen carbonate decomposes: 2NaHCO3 -----> Na2CO3 +CO2 + H2O The key to this problem is to find the no. moles CO2 produced. The equation tells us the no. moles of NaHCO3 will be twice this. We then convert that to grams hence get ...
Total alkalinity measures all carbonate, bicarbonate, and hydroxide alkalinity at a pH 4.5 (approximately). Phenolphthalein alkalinity is measured by titration of the sample to an end point pH of 8.3 which corresponds to the end point of the phenolphthalein indicator.
Total organic carbon is analyzed by placing approximately 0.350 g of dried, ground and homogenized sample into a clean, carbon-free combustion boat. Each sample boat is treated with phosphoric acid drop by drop until the sample stops "bubbling" and the sample is completely moist with acid. The sample is placed into an oven set at 40°C for
Ore Sampling Methods: Good & Proper. Previous Next ... Treating the falling stream of ore as a ribbon, they cut sample-sections directly across its entire width, these portions varying in shape and size with the mechanism employed. Of the many, types that have been invented and patented, only three have come into general use, and Fig. 7 show ...
The goal of assaying and testing any potential gold and silver bearing materials is to determine their metals content. While it is sometimes possible to look at a sample and guess its possibilities, more often than not, in order to have an accurate idea of how valuable in ore is it must be analyzed.
MEASUREMENT OF DOC AND DIC Objectives: In this lab we will measure the concentrations of dissolved inorganic carbon (DIC) and dissolved organic carbon (DOC) in the water samples that were collected at the beginning of the quarter. In doing the measurements, students .
important – e.g., how much iron in an ore sample, how much lead in your drinking water, calcium in intracellular fluids. In a sense, it's the simplest type of analysis, since there are only about 120 possible analytes. But to do the analysis, the sample has to be completely destroyed (chemically and physically) and reduced to individual gas ...
Apr 18, 2013· ok, so the investigation that we are doing it on is about finding how much carbonate is in a sample of ores. our hypothesis is: the amount of carbonate in an ore sample can be measured by adding hydrochloric acid to the sample until it stops fizzing. for my planning sheet i have wrote my method for the actual experiment. I have wrote what equipment I need and i have wrote one risk .
C. Dissolution of Iron Ore Sample and Pre-reduction of Iron(III) 1. Obtain a sample of unknown iron ore from your laboratory instructor. Weigh out three samples of about 0.5 g into 500 mL conical flasks. Add 25 mL of 6 M HCl to each flask; cover with a watch glass and, in the fume hood, heat below boiling until the iron ore
Apr 11, 2018· When you add a hydrochloric acid (HCl) solution to a solution of sodium carbonate (Na 2 CO 3), the hydrogen ion in HCl switches places with one of the sodium ions in Na 2 CO 3 to produce sodium hydrogencarbonate, also known as sodium bicarbonate (baking soda), and sodium chloride (salt).
Determination of Carbonate Concentrations in Calcareous Soils with Common Vinegar Test 2 4. Use the eyedropper to add white vinegar to the soil sample in increments of ten drops at a time, stir the mixture thoroughly, and record the number of drops added. 5. .
A simple method for measuring the carbonate content of soils Article (PDF Available) in Soil Science Society of America Journal 69(4) · July 2005 with 4,343 Reads How we measure 'reads'
Oct 15, 2013· The hypothesis is 'the amount of carbonate in an ore sample can be measured by adding hydrochloric acid to the sample until it stops fizzing. I have to write a method,equipment,risk assessment issues and a context.
important – e.g., how much iron in an ore sample, how much lead in your drinking water, calcium in intracellular fluids. In a sense, it's the simplest type of analysis, since there are only about 120 possible analytes. But to do the analysis, the sample has to be completely destroyed (chemically and physically) and reduced to individual gas ...
Below is an example of the method a scientists would use measure the amount of metal carbonate in an ore. Equipment: • 250 cm3 beaker • Samples of different metal carbonate ore • 25cm3 measuring cylinder • Stopwatch • Spatula • Dilute hydrochloric acid 1 mole per dm3 Method: 1. Measure out an amount of metal carbonate ore. 2.
A method for the determination of sulfate and sulfide sulfur that occur together in rocks or minerals is presented. All the sulfate sulfur is converted to barium sulfate in an inert atmosphere to prevent oxidation of any sulfide sulfur. Cadmium chloride is added to precipitate any sulfide ion that may be liberated.
Dec 28, 2011· An ore of strontium contains strontium carbonate, SrCO3. To obtain metallic strontium, • the SrCO3 is converted into strontium oxide, SrO; • SrO is then reduced to produce strontium. A chemical company receives an order to supply 100 tonnes of strontium. The company needs to work out how much ore to process The ore typically contains 2% by mass of SrCO3.
carbonate ores hydrochloric acid Hydrochloric acid (HCl) is commonly used acid for carbonate acidizing treatments, due to its low cost and fast reaction with carbonate rock types (limestone and dolomite). It is mostly used with the concentration of% (by weight) solution, to .
Arriving at total alkalinity requires an equation (given below) to extrapolate back to the amount of sulfuric acid that was added to actually convert all the bases to carbonic acid. A multiplier (0.1) then converts this to total alkalinity as mg/l of calcium carbonate (CaCO3). To determine the alkalinity of your sample, follow these steps:

How to calculate the percentage of calcium carbonate in sea shells in an experiment [closed] Ask Question ... You should measure the mass of the amount of shell you use at the start. You will be able to figure out the mass of the calcium carbonate in that sample of shells that you use (since you now know the number of moles of calcium carbonate
