You are given an experiment to determine the Hydrolysis of different salts. For this, you take different samples of different salts, add 2-3 drops of different indicator in them and note the color change. Then compare the color change to a color indicator chart to determine the pH of the salt.

What is the GREATEST source of error in an experiment like this? How could you minimize this error?

Answer #1

there are two types of major errors.First one is about the the volume of the indicator added which should be added acuurately rather than in vague manner. In order to monimise this error you can use a micropipette for adding the indicator solution.

The second one is about the intensity of the colour or the amount of colour fade, intensify or change which can not be significantly identified. Inorder to reduce this error possibility you need to to use a spectrophotometer or colourimeter to measure the colour change

Hi there, I did an experiment using the titration of EDTA to determine the hardness of water. 1.)How do I determine the amount of moles of EDTA? 2.)How do I find the average water hardness of the water I used in this experiment? I started with 10 ml of water, added 5 drops of Ph 10 to it, and then EBT indicator. I then used the tirator to dispense EDTA into the beaker to find out if how much EDTA...

In experiment five, the "Identification of Ions in Salts", you will use a series of reactions to identify a cation in one unknown and a cation-anion in another unknown. In this experiment primarily precipitation reactions or dissolving of precipitates will be used. The color and texture of the precipitate will be important to observe. In the identification of the anion the formation of a gas will be used to help ID the anion and a flame test will be used...

In this experiment you will construct a smal electrolytic cell. Then using indicators you will determine the products fromed at the anode and the cathode druing several different electrolysis experiments. About the experiment: in the first part of this experiment you will construct a small scale chlorine production plant. it is a miniature of the real, large scale process used for production of chlorine by the electrolysis of sodium chloride or brine (procedure written by Dr. Stephen thompson, CSU, CO)...

An experiment was performed to compare two (2) types of radiation meters to determine if they provide equivalent readings. Four (4) objects of different materials, temperatures, and sizes were used in the experiment, and radiation readings were taken with each of the meters (one reading for each meter-object combination). The resulting sums of squares are shown in the table below. Consider the null hypothesis that the two meters provide essentially the same readings. With alpha = 0.01, would you accept...

Below is the background info for the lab assignment. The 4 blank boxes are the questions I would like answers too. The end point for the fine titration was 35.90 mL in the burette when the solution turned bright green again. And the coarse titration I got 35.36mL as the end point. 35.9 mL is exact in case you need that info. Thanks! Background In this lab, we will determine the amount of alcohol (ethanol), C2H5OH, in a commercial vodka...

Preparation of acetyl salicyclic acid (Aspirin) post-lab questions 1.) The FeCl3 test you performed on salicylic acid, crude aspirin, and the purified aspirin gave different colors. Comment on the results you obtained in each of these tests in terms of colors and the functional groups present and what does that indicate about the purity of your purified aspirin? I got a dark purple color for saliclyc acid tube. "dark yellow" for crude aspirin tube, "llighter yellow" color for aspirin tube...
