Titration-finding the concentration of a solution of sulphuric acid essay

Reaction 5- The mozzy zinc is a shiny gray and turns dark when added to copper 11 chloride solution. In all of these I will measure my potatoes one at a time, using a ruler. I will use five drops of methyl orange indicator each time. I have chosen this particular piece of apparatus because it will measure in millimetres.

Classifying chemical reaction

Tell us what you need to have done now! When burning the splint is placed on the test tube, the flame is extinguished. I will carefully pour mrs of sugar solution into each of two the beakers of my saturated solution. I will also have to distinguish my pair of concentrations I will also label them alphanumerically.

Thank for reading for Lab Report and i hope you have fun trying all 8 of these experiments. The reactions that occurred in during the experiment were neutralization reactions, meaning that the moles of acid equaled the moles base at the end of the experiment.

Finding out how much Acid there is in a Solution and the Molarity of acid through titration

Previously, I mixed solutions together to see if a reaction would take place. Recorded observations in the data table Reaction 4- 1. A number of different procedures could have been undertaken to ensure the most accurate results possible. The best idea however is to use a control colour so that it is possible to ensure the results all have the same pH reading.

Then it is possible to transfer this into the larger container. Also by making larger quantities of the sodium carbonate solution there is a reduction in the percentage error, as a slight misjudgement has less effect the more substance and solution is being used.

Turned off the safety lighter as soon as the alcohol ignited.

Titration-finding the concentration of a solution of sulphuric acid Essay Sample

The formula I used to obtain the proportions for my concentration: I will put my potato cylinders aside I will consult a table. It takes a short time for the alcohol to burn completely. When using the scales ensure there is nothing effecting the result, even someone leaning on the bench could cause an effect, the digital scales are very sensitive.

I will then take the pipette to the sink and release the solution. If the beaker is left in a warm place then the water may evaporate and this will change the concentration. Keep away from flames and other sources of ignition Notify the teacher and clean up all spills immediately Avoid contact of all chemicals with eyes and skins.

Same type of potatoes i. For reaction 6, Adding a solution of sodium phosphate with copper 11 chloride produces a precipitate. After the scalpel has been used I must insert the scalpel into an unused potato, so that there is no danger of me cutting my self or someone else.

I will need a scalpel to cut my potato cylinders to a precise length of 30 mm. I will need labels to identify my apparatus. These are my variables: Keep the valve open until the solution in the conical flask turns from orange to a skin coloured pink. I will read it off at eye level.

Tests and repeatsAmount of NaCO3 0. In addition, the equipment used could have also contributed to the error as all pieces of apparatus have an uncertainty attached to it. I predict that a reaction rate for a 2M solution Conclusion In conclusion, this experiment found the molar concentration of acetic acid in vinegar to be 0.

I intend to keep my experiment away from extreme sunlight. Worked in the hood or a designated work area. The amount of water inside a cell is called water potential.

If possible, use small measuring apparatus this reduces the percentage error significantly.An acid-base titration is a neutralization reaction that is performed in the lab in order to determine an unknown concentration of acid or base.

The moles of acid will equal the moles of base at the equivalence point. So, if you know one value, you automatically know the other. Here's how to perform. Titration of an Unknown Acid Prepared by Stephen E.

Schullery and Ross Nord, Eastern Michigan University usually to determine the concentration (or amount) of whichever reactant was unknown.
