Lab #16: Gravimetric Analysis of Metal Carbonate Introduction: In this laboratory the identity of group 1 metal Carbonate is determined gravimetrically using a double replacement precipitation reaction. Concepts: Double-Replacement reaction Gravimetric analysis. Background: The identity of group 1 metal M is determined by analyzing an unknown Group 1 metal carbonate‚ M2CO3. There are 3 main reactions in this lab: 1. Equation 1: M2CO3 (s) → 2M+ (aq) + CO32- (aq) 2. Equation 2: Ca2+

Ash Experiment # 5: Volumetric Analysis of a Carbonate – Bicarbonate Mixture Submitted by: Eugenio December 2012 Department of Chemical Engineering University of Santo Tomas España‚ Manila Abstract Soda ash is the common name for sodium carbonate (NaCO3)‚ a chemical salt derived from carbonic acid. It is frequently used in manufacturing‚ industry‚ and in domestic chores. Glass production is one of the primary industrial uses for sodium carbonate. It is also used as an additive for detergents

Build a Fizz-Inflator Purpose of the project: * To know if water temperature affect how fast the balloon fills up. * To know if the size of the bottle affect how much the balloon fills. * To know if the amount the balloon fills-up can be controlled by the amount of vinegar or baking soda. Materials: * 1 small empty plastic soda or water bottle * ½ cup of vinegar * Small balloon * Baking soda * Funnel or piece of paper Hypothesis: * Yes‚ the higher the temperature

3/16 Chem 322 Friday Partition Coefficient (Extraction) Lab for Benzoic Acid Reaction Mechanism: Purpose: The purpose of this particular lab was to demonstrate the difference in separation of Benzoic acid in water and Dichloromethane. Also the difference in separation of Benzoic acid in bicarbonate and Dichloromethane. By calculating the partition coefficient for each of these separations‚ it became clear the differences in the separation of the aqueous and organic layers. Observations

In its mineral form sodium chloride‚ NaCl‚ is known as common salt. It is important because it is essential to the health of human beings and of animals. for domestic use it is fined down to what is known as table-salt‚ and small quantities of other chemicals are added to it to keep it free-flowing when in contact with the atmosphere. Salt and potassium are combined to produce iodised salt‚ used when iodine is lacking in diet. It’s absence cause goitre‚ the swelling of the thyroid gland. Livestock

of water in the given ionic hydrate? (Na2CO3.xH2O) Background Information: Sodium Carbonate also known as Washing Soda (Na2CO3.xH2O) is a sodium salt of carbonic acid. Sodium carbonate is domestically well known for its everyday use as a water softener. It is also used to remove grease‚ oil and wine stains. It can be extracted from the ashes of many plants. It is synthetically produced in large quantities from salt (sodium chloride) and limestone in a process known as the Solvay process. Titration

Alkali Metals Introduction Alkali metals refer to six elements belonging to the Group IA of the long form of the Modern Periodic Table‚ viz. Lithium (Li)‚ Sodium (Na)‚ Potassium (K)‚ Rubidium (Rb)‚ Cesium (Cs) and Francium (Fr). Fr is a radioactive element. These elements are called so because they form strongly alkaline oxides and hydroxides. Electronic Configuration of Alkali Metals Each of the alkali metals has one electron in their outermost (valence) shell‚ which is just outside an inert
