Experiment 6: The Standardization of a Basic Solution and the Determination of the MM of an Acid
Experiment 6: The Standardization of a Basic Solution and the Determination of the MM of an Acid *Note: This experiment is relatively long unless you know precisely what to do. Read the experiment before coming to class and arrive on time. After reading through the experiment answer the following question: 1. 7.0 mL of 6.0 M NaOH are diluted with water to a volume of 400 mL. You are asked to find the molarity of the resulting solution. a. First find out how many...

In a titration using methyl orange as an indicator 25.0 cm of a solution of 0.1 M sodium hydroxide reacted with 25.0 cm of 0.1 M phosphoric acid, H3PO4, solution. If the experiment is repeated using phenolphthalein in place of the methyl orange as the indicator the volume of the sodium hydroxide used to cause the indicator to change colour is 50.0 cm'. This is because phenolphthalein changes colour when a different number of hydrogen ions in the acid have...

The concentration of each solution will be given in molarity (M). Molarity is a quantity that expresses the moles of solute present per liter of solution. A sodium hydroxide solution is labeled as 0.1020 M. i. Write that as a ratio of moles and liters. ii. If 11.25 mL of the 0.1020 M NaOH solution is used to titrate a solution, then how many moles of NaOH does that represent? iii. If the number of moles of unknown acid neutralized are determined to...

Question 6 1 pts What is the molarity of a solution made by adding 2.213 grams of KHP (MM=204.2 g/mol) to 50 mLs of water? Question 5 2 pts Look again at the simulation page. Notice how we know the exact concentration (in M) of KHP but we don't know the exact concentration of NaOH and instead only have a general number (about 1M NaOH). Using your answers to the questions above and the fact that moles of acid =...
