In this lab, we assumed that the only acid in our juice sample was citric acid, but other acids may be present as well. ascorbic acid (vitamin c) is another common acid found in fruit juices. how does the presence of other acids in our juice sample affect our calculated concentration of citric acid? choose one answer from below. choose one answer from below. the presence of other acids in our juice causes our calculated concentration of citric acid to be falsely low. the presence of other acids in our juice causes our calculated concentration of citric acid to be falsely high. the presence of other acids in our juice does not affect our calculated concentration of citric acid.

What type of specimens where you able to see under each of the microscopes in the microscope activity

You have been asked to lead a demonstration for the undergraduate microbiology lab course about the uses of negative staining when studying bacteria. a "negative" stain does not stain the bacterial cell itself but stains the space between cells. under magnification, the acidic (negativelycharged) nature of the stain will be repelled by the negatively charged bacterial cell wall and willleave the cell colorless in a stained background. negative stains are used primarily to reveal the presence of negatively charged bacterial capsules; therefore, they are also called capsule stains. encapsulated cells appear to have a halo surrounding them. the negative stain procedure does not require heat fixation, which limits any chances of alteration in bacterial cell shape and size. the bacterial suspension is added to a drop of stain, such as nigrosin or eosin, and drawn across the glass slide using a coverslip.nigrosin staining-not safranin staining-of klebsiella pneumoniae will allow for the visualization of the cell shape and the determination of the presence of a capsule.true/false
