Which of the following statements about blood acid/base balance is true? Select one: a. Carbonic anhydrase is a membrane protein that transports bicarbonate ion from the filtrate into the tubular epithelium b. The phosphate buffer system is the primary extracellular buffer c.

you select the amino acid Cysteine (pKa=8.2) and dissolve 0.1 moles in 1 liter of water in order to make a buffer solution. You then adjust the pH to 7.2, but then accidentally add 0.03 moles of HCl to the solution. is the solution still a good buffer? Please help me understand how to use the number of moles added to solve the problem. I can't seem to understand how the amount of moles added relates to the amino acid's...

1)Sodium hydroxide cannot be used to prepare a primary standard titration solution because the compound is not available in high purity. The most common impurity is water because sodium hydroxide is hygroscopic meaning it absorbs water from the air. a)If sodium hydroxide that had aborbed water was used directly to prepare a standard solution how would the actual concentration differ from the presumed concentration? B)If this sodium hydroxide standard solution was used to titrate a hydrochloric acid solution of unknown...

Acid-Base Behavior In addition to following the general safety rules, chemicals need to be handled properly. In particular, two very important classes of compounds called acids and bases require special attention. These compounds are commonly used reagents in the laboratory; therefore, understanding their proper disposal is beneficial. Physical differences between acids and bases can be detected by the some of the five senses, including taste and touch. Acids have a sour or tart taste and can produce a stinging sensation...
