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...
It's a weak acid strong base titration Experiment 4: Identification of an unknown acid by titration Page 2 of 15 Background In this experiment, you will use both qualitative and quantitative properties to determine an unknown acid's identity and concentration. To do this analysis, you will perform a titration of your unknown acid sample-specifically a potentiometric titration where you use a pH meter and record pH values during the titration, combined with a visual titration using a color indi- cator...
please help me speciqlly with 11. 12. 13. 14 Experiment 7, Analysis of KHP by titration with NaOH Wright College, Department of Physical Science and Engineering In this experiment, you will determine the amount (percent) of potassium hydrogen phthalate (KHP) that is in an impure sample. You will determine the percent of KHP via titration using NOH with known inolarity. The reaction will follow, KHCgH00, (aq) + NaOH (aq) ---------> KNaCHO, (aq) + H20 (I) At the end point, the...
CH 111 - Exp 6 Titration of Fruit Juice(2) (2) (Protected View) - Word (Unlicensed Product) Help Tell me what you want to do This experiment is highly similar to the titration of HCI with NaOH so there is no video accompanying this lab. In this titration orange juice is used as the acid in place of HCI. That is because most fruit juices are acidic, with citric acid (H3C6H5O7) being one of the more common acids, especially and not...
As part of Lab 11 you will make and standardize a solution of NaOH(aq). Suppose in the lab you measure the solid NaOH and dissolve it into 100.0 mL of water. You then measure 0.1993 g of KHP (204.22 g/mol) and place it in a clean, dry 100-mL beaker, and then dissolve the KHP in about 25 mL of water and add a couple of drops of phenolphthalein indicator. You titrate this with your NaOH(aq) solution and find that the...
Pre-laboratory Assignment Name: Read the experiment and answer the following questions as directed by your instructor. 1. In this experiment, you will use potassium hydrogen phthalate (abbreviation KHP, formula HKCH.0) to standardize (to determine the concentration precisely of) the NaOH solution. What is the molar mass of KHP? 2. In Part 1, you will titrate a weighed mass of KHP (dissolved in water) with the unknown NaOH solution. What data must you collect in order to find [NaOH)? List the...
2 &3 Read the experiment and answer the following questions as directed by your instructor. 1. In this experiment, you will use potassium hydrogen phthal ate (abbreviation KHP, formula HKCsH4O) to standardize (to determine the concentration precisely of) the NaOH solution. What is the molar mass of KHP? 2. In Part I, you will titrate a weighed mass of KHP (dissolved in water) with the unknown NaOH solution. What data must you collect in order to find [NaOH]? List the...
5. An average value of the mo lar mass for the unknown acids used in this experiment is about 300 g/mol. You have determined the standardized concentration of your Na OH solution. You know that you would like to use about 15 mL of this solution to titrate your unknown acid. Using the fact that the number of moles of NaOH is equal to the number of moles of the unknown acid (because the unknown acid is monoprotic), compute the...
