Quantitative Analysis of a Soluble Sulfate Steven English Lab Instructor: Dr. Campo Date: Tuesday‚ February 5th 2013 Pre-Lab Questions A. Adding the acid to the sodium sulfate solution results in an increase in the solubility of any free anions present in the sample. This will happen because the present anions will bind with the hydrogen cations present in the acid. B. The sodium sulfate is boiled because experiments have shown that barium sulfate is 50 times more soluble at 100°C

SODIUM gSodium is a chemical element with the symbol Na (from Latin: natrium) and atomic number 11. It is a soft‚ silver-white‚ highly reactive metal and is a member of the alkali metals; its only stable isotope is 23Na. The free metal does not occur in nature‚ but instead must be prepared from its compounds; it was first isolated by Humphry Davy in 1807 by the electrolysis of sodium hydroxide. Sodium is the sixth most abundant element in the Earth’s crust‚ and exists in numerous minerals such

samples‚ respectively‚ produced a percentage of 50.32% and 35.06% SO3-; averaging a net percentage of 42.69% with a standard deviation of ± 10.79%. Purpose The purpose of this experiment is to determine the mass of sulfate in the precipitate from the reaction of BaCl2 (aq) + SO42-(aq) → BaSO4(s) + 2Cl-(aq) while utilizing gravimetric analysis methods. Introduction Gravimetric Analysis utilizes the mass of a product to calculate the quantity of the original unknown

this goal by creating five reactions containing Sodium Sulfate that would confirm our compound and show its chemical properties. In each reaction‚ we replaced the presence of Sodium Sulfate with our unknown. Our first reaction was the reaction from the sulfate anion test between Sodium Sulfate and Barium Chloride. If the compound was in fact Sodium Sulfate it would produce a white precipitate and it did. The second reaction was first between Sodium Sulfate and Hydrochloric Acid‚ and then Silver Nitrate

Sodium chloride‚ also known as salt‚ common salt‚ table salt‚ or halite‚ is an ionic compound with the formula NaCl. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible salt‚ it is commonly used as a condiment and food preservative. [edit] Properties Thermal conductivity of pure NaCl as a function of temperature has a maximum of 2.03 W/(cm K) at 8 K and decreases to 0.069 at 314

Abstract In this experiment‚ the Ksp for calcium sulfate dihydrate‚ CaSO4·2H2O‚ by titrating 4 times a calcium sulfate dihydrate solution with diprotic EDTA‚ H2(EDTA)2-. For each trial we found the Ksp by means of molarities and activities. The results for the Ksp using only molarities was very different than the Ksp using activities. The average Ksp using molarity only was 2.26 x 10-4 and the average Ksp using activity turned out to be 2.31 x 10-5. The actual Ksp however‚ is 3.14 x 10-5. A percent

Sodium‚ one of many elements in the periodic table is being used in everyday life‚ it is also an essential element within your body. It is just another element‚ but one of the differences is that this element is something that most people consume every day. Sodium has played an important role in everyday life because of its uses in medicine‚ industry‚ and agriculture(Shriver). Sodium was discovered in 1807 by a man named Sir Humphrey Davy. He was well known for his discoveries of most alkali metals
