A lab technician wants to make 500 mL of a 2.50 mol/L solution from a standard solution of concentrated sulfuric acid. Drag and drop to put the steps, of the preparation of a solution by dilution, in the correct order. Step 1 Step 2 Step 3 Step 4 Step 5 Calculate the volume needed of the concentrated sulfuric acid solution. Place 250 mL of distilled water into a 500 mL volumetric flask. Pipette the calculated volume of the concentrated sulfuric acid solution into the volumetric flask. Top up the solution with distilled water until it reaches the 500 mL meniscus line. Stopper and invert the flask to mix. Place 250 mL of distilled water into a 500 mL Erlenmeyer flask. Place 250 mL of tap water into a 500 mL Erlenmeyer flask. Place 250 mL of tap water into a 500 mL volumetric flask. Add 250 mL of distilled water to the concentrated sulfuric acid solution in the 500 mL volumetric flask. Use a graduated cylinder to measure the calculated volume of the concentrated sulfuric acid solution.

given a diluted acid solution that was tested by another student. They were supposed to make a solution with a certain concentration. If your experimental data matched the test but not the target concentration, what does that tell you about the data? For example, the student was supposed to make a 0.87 M solution. When they tested it, they got 0.6113 M. When we tested it,we got 0.6144 M.

Antony determine the pH of a solution to be 6.8. What is the concentration of hydronium ions in this solution? Show your work.

the sig figs is wrong. what will be the correct sig figs?

To do a chemistry experiment, you need to prepare 350mL of 0.25M NaOH. There is one small problem: you do not have any 0.25M NaOH. However, all is not lost, it has been discovered that you do have a stock supply of 6M NaOH in your cupboard. How do you prepare the solution you need? (Write a recipe for making the solution as the final step. )

The acids and bases used in the first part of this experiment were strong acids and strong bases. What is a weak acid or base? simple plz

An acid will always neutralize a base to form a salt and water.   True or False?
