What will be the conclusion of the test if no precipitate forms? Lead(II) ions are not present in solution. Lead(II) ions are present in the solution. Lead(II) ions are present, but in a very small concentration. More sodium nitrate solution needs to be added before a conclusion can be made. No conclusion can be made in this test. 围 1 11:14

Continued... 5. Answer ALL parts of this question The stability of chloramphenicol in eye drops is being studied at different temperatures and times. The concentration (in mg/L) of chloramphenicol at three different temperatures over time is provided below. Time (day) -18°C 25°C 40°C 25 28 23 7 27 20 20 30 20 21 20 180 23 25 19 (a) Using the data in the tables below assess and explain if the reaction time (after 1 hour of the start of the reaction) was an important factor affecting the yield of the reaction and provide the null hypothesis of the statistical test carried out. (b) The amount of chloramphenicol at -18 °C seems to vary with some values appearing to be higher than others. Explain what may be causing this variation AND suggest a methodology to identify if there was a systematic error in the measurement. ||

The two must be done independently of each other, as they are completely unlike. A qualitative analysis must always be done before a quantitative analysis. A quantitative analysis must always be done before a qualitative analysis. A qualitative analysis identifies the type of ion in solution and the quantitative analysis will determine how much of this ion is present. A quantitative analysis identifies the type of ion in solution and the qualitative analysis will determine how much of this ion is present. i 11:15

The students conducted the assay for LDH activity using the two serum samples. Each cuvette (path length 1 cm) contained 3ml of a suitable assay buffer (including pyruvate as substrate). 20 microlitres of either serum was added to the cuvette and the absorbance values immediately recorded at the optimum wavelength for a period of 5 minutes (absorbance readings taken every 30 seconds).   Protein concentration of serum sample (mg/ml) Change in absorbance at optimum wavelength per minute Control serum (C) 8 -0.04 Diseased serum (D) 7.8 -0.6 1c. Using the molar absorption coefficient of NADH as 6220 M-1 cm-1, and by application of the Beer-Lambert law, estimate the enzyme activity in the two samples (C and D). Express activity as moles per second.  1d. Estimate the specific activity of the two samples (moles per second per microgram).

A 10.00-g sample containing an analyte was transferred to a 250-mL volumetric flask and diluted to volume. When a 10.00-mL aliquot of the resulting solution was diluted to 25.00 mL it was found to give a signal of o.235 (arbitrary units). A second 10.00-mL aliquot was spiked with 10.00 mL of a 1.00- ppm standard solution of the analyte and diluted to 25.0o mL. The signal for the spiked sample was found to be o.502. Calculate the weight percent of analyte in the original sample.
