Failure to sign this declaration will cost you 5 points. Signature: %)/\_'/\, Purpose and Method Things to think about: What is the goa! of this experiment? Explain how it is accomplished. What is the gensral method (not step by step detailed procedure) that you will be using to achieve this goal? How will you process the datal that you record in lab? (What calculations will you use and how do you obtain all of the values to plug into those equations?) (& fl?intS) 'The goal of this experiment is to determine the accuracy of measurement using three tools for measuring the voiume of water: graduated gylinder, buret, and-pipet. We will use each type of glassware to measure and deliver 10mL of water into a vial, and proceed to weigh and record the mass of the samples. This procedure will be repeated several times, and mass data that is gained will be used to calculate the volume of the water delivered, average volume of water delivered, and standard deviation of measurements, Secondly, we will prepare a sucrose solution that is 25%.sucrosa by weight. We will use our most precise measuring device to caiculate the density of our solution {using the mass we measure and volume we of water we determine to use) and then compare it to the known density value to then determine the accuracy of the buret. In conclusion, we will calcuate the volume of a sample of mystery.metal.using a gradualted cylinder and measuring the inital volume of the water and subtracting it from the volume after the metal was added. We will use these values along with the mass of the sample to compare to other known values and determine what metal it most closely resembled. For each part of the experiment we will use the data we measure to find t@m _standard deviatiors of our measurements, thus determining the accuracy of each measurement tool.

Explain your reasoning and include the evidence you have for your decision. (2 pts) We found that the pipet was the type of glassware that provides the best precigicion. We determined this because our average volume of water delivered was 9.985mL, closest to the desired 10mL. We verified this result when we calculated the standard deviation of our data and found that it was the closest to 0, meaning that the pipet indeed was the most precise piece of glassware used for measuring. {V.

What is the main difference between a qualitative analysis and a quantitative
analysis of a solution?
The two must be done independently of each other, as they are completely
unlike.
A qualitative analysis must always be done before a quantitative analysis.
A quantitative analysis must always be done before a qualitative analysis.
A qualitative analysis identifies the type of ion in solution and the quantitative
analysis will determine how much of this ion is present.
A quantitative analysis identifies the type of ion in solution and the qualitative

8) In the reversible reaction [Co(H,O)6]²*(aq) + 4CI (aq) +→[Co(H,O),Cl4]² (aq) + 4H,O(1), the initial color
of the reaction mixture was pink.
When concentrated HCI (aq) was added to the reaction mixture, the color changed to purple.
Which reactant is purple and why?
a) [Co(H2O)6]²*(aq) is purple because it is a cobalt compound
b) [Co(H2O)6]²*(ag) is purple because adding Cl (as HCI) shifted the reaction towards
products
c) HCl is purple because adding it turned the reaction purple
d) [Co(H2O),ClĄ]? (aq) is purple because adding CI (as HCI) shifted the reaction towards
products
