AP Chemistry Dr. Istone Lab 3: Gravimetric Analysis of a Metal Carbonate Lab Objective: In this lab we will determine the identity of a group 1 metal carbonate compound by gravimetric analysis. The unknown is weighed and dissolved in water and the precipitate is filtered‚ dried‚ and weighed. From the data the formula weight and identity of the unknown metal carbonate is determined. Lab Procedure: 1. Set up the Bunsen burner and ring clamp‚ light the burner and heat the crucible

In this experiment‚ gravimetric analysis will be used to determine the unknown metal carbonate. Gravimetric analysis. Gravimetric analysis is a method where an ion being analyzed can be classified through their mass (Yoder 2018). Due to the fact that carbonates can be hygroscopic‚ which means it would be able to absorb water from water vapor‚ extra precautions have to be taken place to be able to get an accurate mass (Helmenstine 2017). This can be done by using a drying oven and a desiccator. A

speed of a metal carbonate breaking down depends on where the metal is in the reactivity series. The more reactive a metal is the slower it takes for it to breakdown. The less reactive a metal is it breaks down faster. Explain the hypothesis using scientific ideas: The metal carbonate which is lower in the reactivity series such as copper can thermally decompose much faster because it is the least reactive metal so its an unstable carbonate and the bonds are much weaker. So the metal that is

Title: Grip Strength and Muscle Fatigue I. Purpose/Hypothesis: In this lab the subject will grip on a scale that measures the amount of force being put on it. We will observe the change in hand strength during continuous grip over time. Then we will also measure hand strength during rapid‚ repetitive gripping. I believe that hand strength will weaken during a continuous grip more than if you were to keep a repetitive grip. II. Procedure: 1. Connect the Hand Dynamomenter to LabQuest and select

Rupprecht Date(s) performed: October 2 - 3‚ 2012 Gravimetric Analysis of an Unknown Group 1 Metal Carbonate Purpose: The purpose of this lab is to determine the identity of a Group 1 metal carbonate compound by gravimetric analysis. Procedure: The unknown carbonate is weighed and then dissolved in water. A solution of CaCl2 (calcium chloride) is added to the metal carbonate solution to precipitate the carbonate ions as CaCO3 (calcium carbonate). The precipitate is then filtered‚ dried‚ and weighed

Courtney Jablonowski Dr. Peterson Lab Report 1 June 17‚ 2012 Results The tooth formula is a shorthand technique that biologist use to keep track of the teeth on a particular jaw. The formula consisted of two lines‚ top jaw and bottom jaw‚ which were used to count how many incisors‚ canines‚ premolars‚ and molar teeth a species had. Species A‚ Odocoileus virginiaus (white-tailed deer)‚ had a tooth formula of 0033/3133. On the top jaw‚ the deer had zero incisor and canine teeth but have

Quantitative Determination of Gravimetric Analysis Ophelia Low Gek Suan 1311907DBT/FT/1A/01 | SYNOPSIS By gravimetric analysis‚ we are able to determine the amount of sulphate in barium sulphate quantitatively. We can do so by slowly adding dilute barium sulphate to an unknown sulphate solution that has been heated and acidified with concentrated hydrochloric acid slightly. A white precipitate will be yield from filtering the solution
