Phenolphthalein turns pink in solutions that are roughly 1.0 x 10^-5 M in hydroxide ions. The only source of hydroxide ion is your Ca(OH)2. Let's assume the amount of water left behind in the beaker to test for complete transfer is about three drops, or .15 mL. What % of the solution/solid was transferred over to the container?

Answer #1

This question is incomplete to calculate the % of the solution/solid was transferred over to the container?

We will need some value on the weight or something similar to start from

The only values given are the concentration of the OH- which is 1.0 x 10^-5 M in hydroxide ions. So the concentration of the OH in the three drops left behind is also 1.0 x 10^-5 M in hydroxide ions. The amount of solution transferred is also 1.0 x 10^-5 M in hydroxide ions.

From tjis we cannot calculate the % of soltuion transferred.

PLEASE ANSWER ALL PARTS OF THE BOTTOM PART B B. Calcium Hydroxide Titration Use a pipet to withdraw 20.00 mL of a saturated solution of Ca(OH)2 and place it in a 150 mL Erlenmeyer flask. Add three drops of phenolphthalein indicator. Fill the buret to the zero mL mark with 0.10 M HCl solution and titrate the hydroxide solution until the mixture turns colorless.    Record the buret reading at the end point. Repeat steps 1- 4.

I have provided the information for the lab below. I want to see the chemical reactions that take place during each step of the experiment. So in the procedures when a chemical was added i would like to see what the products and byproducts that were formed. I also want to see one over all reaction for this experiment to just get an overview of what exactly is happening during the experiment. Thank you:) Part B: Synthesis of [Co(NH3)5Cl]Cl2 Objective:...
