Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.

Question

2. At SATP, the theoretical K, value for ethanoic acid is 1.8 x 105 in pure water.
A) Calculate percent error of the K, you determined to this standard value.
% Error Theoretical Value - Experimental Value
Theoretical Value
X 100
B) Suppose that you used an indicator that fell in the buffer zone of the titration curve. Explain how the
source of error either increased or decreased the Ka that was derived from experimental data.
3. Based on your results, calculate the pH of the solution at equivalence point. Comment on this pH (i.e. why
is it neutral, acidic, or basic). Remember the K, = 1.8 x 105.

For each scenario below, select the color of the solution using the indicator thymol blue during the titration. When you first add indicator to your Na2CO3 solution, the solution is basic (pH ~10), and the color is [Select] At the equivalence point for the titration, the moles of added HCI are equal to the moles of Na2CO3. One drop (or less!) past this is called the endpoint. The added HCI begins to titrate the thymol blue indicator itself. At the endpoint, the indicator color is [Select] When you weren't paying attention and added too much HCI (~12 mL extra), the color is [Select] When you really weren't paying attention and reached the second equivalence point of Na2CO3, the color is ✓ [Select] blue yellow red orange green Question 9
The buffers had a strong base added so that they both reach equivalence point. Buffer F has 100mL of 0.01M to it while Buffer G has 2.1mL of 0.5M NaOH. Determine the buffer capacity in moles for both buffers AND indicate which is stronger.

Build a titration curve for the following scenarios. Make sure to label your accesses and anyother appropriate pieces of data. Each curve should have a minimum of 4 data points, but youcan use the following to help structure your curvea) Initial pHb) pH at Veqc) pH=pka (if applicable)d) pH when excess titrant is addede) Additional pH point near Veq for Strong Acid/Strong Base titrations (in order to see thesteepness of the slope) OR additional pH point in buffer zone for titrations with a Weakcompound.
