1.) Write a step-by-step procedure for how to make the following solutions in the lab (pretend you are creating this procedure for someone unfamiliar to chemistry and making solutions; be specific in your procedure and show your calculations):
a.) Create 100.0 mL of a 0.024 M solution of potassium iodate from a 0.048 solution of potassium iodate.
b.) Create 100.0 mL of a 0.016 M solution of sodium hydrogen sulfite from a 0.032 M solution of sodium hydrogen sulfite.
3.) In Part E you will set your reactions to music. Select an appropriate piece of music and time that you will want to see color changes (4 times during the music). Explain what you will need to consider in order to have a color change at these specific times.

Each week before you have chemistry lab, someone needs to prepare all the solutions you will use in your experiment. Suppose your experiment for next week calls for 0.500 M NaOH solution, 3.00 M NH4Cl solution, and 0.100 M Na3PO4 solution. Calculate the mass in grams for each solute that would be needed to prepare 8.00 L of each of the solutions. Calculate the mass, in grams, of solute present in each of the following solutions: a. 225 g of...

A student following the procedure in this lab prepared 4 solutions by adding 12.00, 23.00, 26.00, and 34.00 mL of an 8.25 x 10-2 M NaOH solution to 50.00 mL of a 0.150 M solution of weak acid. The solutions were labeled 1, 2, 3, and 4 respectively. Each of the solutions was diluted to a total volume of 250 mL with DI water. The pH readings of these solutions were: (1) 6.38 (2) 6.73 (3) 6.80 (4) 6.98 PRE-LAB...
