To Study the Relative Reactivity of Metals using Salt …
The elements potassium, sodium, lithium and calcium are very reactive and they react with cold water to produce hydroxides and hydrogen gas. The elements magnesium, aluminium and iron are also considered as active metals and they react with steam to produce oxides and hydrogen gas.

34 5A Experiment 1. A single example of an acid reacting with a metal will be performed and the products noted. 2. Add 50 mL of concentrated HCl (12 M) to 50 mL of water to make 100 mL of 6 M HCl (save excess for later). 3. Using a 125 mL Erlenmeyer flask
The amount of calcium ion in a dietary calcium supplement will be determined by titration with the standard ethylenediaminetetraacetic acid solution (EDTA). Introduction The concentration of calcium ion in the blood is very important for the development and preservation of strong bones and teeth.

Lu Le Laboratory: Synthesis of 1-Bromobutane from 1 …
Calcium chloride is the drying agent of choice in this reaction because it forms complexes with any residual alcohol, as well as with water. After drying, the 1-bromobutane is purified by distillation.
The chemistry of limestone
Some of the calcium hydroxide dissolves in the water producing an alkaline solution called limewater. Ca(OH) 2 (s) + (aq) → Ca(OH) 2 (aq) On blowing into this solution through a straw, the calcium hydroxide solution reacts with the carbon dioxide in exhaled breath to form a cloudy precipitate of calcium carbonate (this is the basis of the limewater test for carbon dioxide).

This is a lab report for my General Chemistry class. The assignment was to create a formal lab report that expresses data and observations, lab procedure, and a discussion of the data that leads to a conclusion. This particular lab report demonstrates my ability to
How would you expect calcium carbonate to react with …
The general formula for an acid reacting with a carbonate is: Carbonate+Acid--->Carbon dioxide+Water+Salt These general equations should be learnt by heart to make exams easier. Due to the formation of carbon dioxide, there would be effervescence. The solid
Reaction of Aluminum with Water to Produce Hydrogen
Introduction: The concept of producing hydrogen by the reaction of certain metals with water was first proposed in the late nineteenth century (1). In more recent times, a paper by Smith in 1972 described an approach using an amalgamated aluminum surface (2).
Reactions Rates - Calcium Carbonate and Acid - Activity
The flask contains 20 g of calcium carbonate chips, and the simulation is paused when it is loaded up. This is so you can start all of the experiments at the same time so they are a fair test. Add 125 cm 3 , 1.0 M hydrochloric acid to the flask, and click the pause button on the main toolbar to start the simulation.

5 Sample Calculations (Cont.) Water Hardness Analysis Example 3 A 100 mL (0.100 L) sample of tap water was titrated with 0.0100 M EDTA solution.The corrected titration volume was 14.80 mL (0.01480 L). Determine the total hardness in mg / L = ppm of calcium carbonate.
Water Hardness - Department of Chemistry
The water is treated with a coination of slaked lime, Ca(OH) 2, and soda ash, Na 2 CO 3. Calcium precipitates as CaCO 3, and magnesium precipitates as Mg(OH) 2. These solids can be collected, thus removing the scale-forming ions from the water supply. .

Neutralization Reaction Lab Answers
9 · An unknown reacting with HCl will be determined (two trials). 194 Equivalence Point pH The pH of the salt and water products of the neutralization reaction = the equivalence point pH. Essentially, since the complete neutralization of HCl requires an equivalent #moles of NaOH, you can calculate the #moles HCl originally present by determining how many moles of NaOH you.
