A multitude reactions occur in this portion of the lab. In the first section of the experiment, a small sample of sodium carbonate is placed in a test tube. Several drops of 6 M HCl are added. Observe what occurs and record the data, noting the odor and the color of the gas that forms. Repeat another reaction with sodium sulfite and record observations. Again, repeat with zinc sulfide. Starting a separate experiment, 6 M HCl is added to 1 mL of 0.1 M lead nitrate.
The purpose of this experiment involved synthesis of diphenylmethanol using phenylmagenisum bromide and benzaldehyde, using the method called Grignard reaction. Grignard reactions are an important method for new carbon-carbon bond formation as well as for the synthesis of alcohols.
Cu (aq) + 2NO3 (aq) + 2Na+ (aq) + 2OH- (aq) → Cu(OH)2 (s) + 2Na+ (aq) + 2NO3(aq)
What were we trying to accomplish with this experiment? What method did we implement to accomplish the task? What techniques were used to purify and identify the product(s) of the reaction?
The cationic surfactant molecules obtained from Mannich bases possess excellent fungicidal property along with good biocidal property against Gram-positive
To complete this lab several chemicals must be measured and transferred to test tubes. First 5.0 mL of 0.200 M Fe(NO3)3 must be diluted to a total volume of 50 mL in a flask. Next 0.0020 M SCN–. This solution is then added to 4 test tubes in 1 mm increments. Each test tube is then put in to
Observations: There was a fizz that occurred in the test tube which means a gas was produced. Also the mixture became warmer, and when putting the lit piece of wood in the tube, the flame went out immediately making a noise, which means that there was no oxygen
Experiment is to investigate the rate of reaction between hydrochloric acid and calcium carbonate Hydrochloric acid + Calcium Carbonate Þ Calcium Chloride + Water + Carbon Dioxide 2HCl (aq) CaCo3 (s) CaCl2(s) H2O (aq) CO2 (g) There are a number of variables in this experiment and these are listed below as input variables and outcome variables.
For this experiment, you will add the measured amount of the first sample to the measured amount of the second sample into its respectively labeled test tube then observe if a reaction occurs. In your Data Table, record the samples added to each test tube, describe the reaction observed, if any, and whether or not a chemical reaction took place.
Chemical kinetics is a branch of chemistry that involves reaction rates and the steps that follow in. It tells you how fast a reaction can happen and the steps it takes to make complete the reaction (2). An application of chemical kinetics in everyday life is the mechanics of popcorn. The rate it pops depends on how much water is in a kernel. The more water it has the quicker the steam heats up and causes a reaction- the popping of the kernel (3). Catalysts, temperature, and concentration can cause variations in kinetics (4).
The rate of any reaction is exponentially related to the concentration of reactants. This lab investigated the reaction of potassium iodate and sodium bisulfite. The experiment was done in order to determine the order of the reaction. Ten trials were done in which ten wells were filled with ten drops of sodium bisulfite with a constant concentration while various concentrations of ten drops of potassium iodate were added to each well of sodium bisulfite. The dilutions of potassium iodate were done in ten wells as well. The first well was filled with a maximum of ten drops of potassium iodate and decreased by one drop for each consecutive well until only one drop was in the last well. For the distilled water, the first well which was filled
carbonate and hydrochloric acid,. I will look at the various factors. affecting the reaction and select one variable to change, while the others keep constant in order to carry out a detailed investigation. Formulae = ==

Hydrochloric acid + calcium carbonate arrow calcium chloride + carbon dioxide + water. HCl(aq) + CaCO3(s) arrow CaCl2(aq) + CO2(g) + H2O(l) Things that affect the reaction rate of this experiment are: 1. The temperature of the hydrochloric acid. 2.
I predict that the following reaction will occur: [IMAGE]CaCO3(s) + 2HCl(aq) CaCl2(aq) + H2O + CO2(g) I also predict that after a certain amount time all the reactants will run out and only the product will be left, only then will the reaction end. Variables A variable is anything which affects the results of an experiment, for example, the variable could affect the speed the particles move or the amount of energy needed in a reaction. For this experiment, there are many variables we could use.
In this experiment three different equations were used and they are the Stoichiometry of Titration Reaction, Converting mL to L, and Calculating the Molarity of NaOH and HCl (Lab Guide pg. 142 and 143).
