The amino acid glycine is often used as the main ingredient of a buffer in biochemical experiments. Based on the pKa values for glycine, in what pH ranges can glycine be used as an effective buffer? In a 0.1M solution of glycine at pH = 9.0, what fraction of glycine has its amino group in the NH form? What volume of 5MKOH must be added to 1L of 0.1M glycine at pH = 9 to bring its pH to 10.0 ?

SELECT correct responses only 1) Volume percent (v/v%) is temperature-independent. 2) There are three major approaches to expressing solution concentration in terms of percent concentration: weight percent, volume percent, and weight/volume percent. 3) Weight/volume percent (w/v%) is a unit-less quantity. 4) The term 'percent' refers to 'parts per thousand'. 5)A standard solution is a reagent of known concentration that is used to carry out a volumetric titration. 6) The endpoint of a titration is the theoretical point reached when the amount of added titrant is chemically equivalent to the amount of analyte in a sample. 7) A substance that changes color in response to chemical equivalence is known as an indicator. 8) Given a sufficiently diligent and experienced experimenter, it is sometimes possible to reach a titration volume error value of 0.

Question 5 In Step 8 (see below, as well as in the presentation), three different slimes were prepared by adding different amounts of borax solution. Which of the following statements is/are correct? Step 8: Prepare the following slimes and evaluate their properties Sample 1 3 PVA solution 40 mL 40 mL 40 mL Borax solution 10 mL 5 mL 1 mL Deionized water O mL 5 mL 9 mL Breaking length Bounce height 30cm 70cm NA 5cm 10cm NA O The more borax we add, the more rigid the slime will become. O The less borax we add, the less elastic the slime will become. O The change in its properties is due to the added amount of water which will affect the structure of the slime. O The water is added in order to have the same final volume of reactants.
