For a concentration technique, Stotal is given as 19.31 ± 0.035, Smb is 0.22 ± 0.008, and kA is 0.154 0.007 ppm, where Stotal is the signal, KA is the method's sensitivity for the analyte and Smb is the signal from the method blank. If we want the absolute percent uncertainty of the concentration CA to be 2.6%, which statement is false below? (Hint: refer to sections 4B.1 and example 4.7 in your textbook) We must improve the uncertainty in kA to 10.004 ppm. O Uncertainty in the method's sensitivity dominates the absolute uncertainty. Improving the signal's uncertainty will improve the absolute uncertainty.

25 ml of pickled brine was taken from an apple pickled with vinegar and diluted to 500 ml, 25 ml of this was taken and acidity was determined with 0.2 N (Factor: 1.05) NaOH. In the main trials, 6.3 ml - 6.5 ml - 6.9 ml, respectively, 0.1 ml base was used in the analysis without using the sample.For example, how many ppm is its acidity?
I solved A, but do not know how to solve B!

a) To prepare 250mL of 0.100 M H2SO4, a student uses graduated pipette and a 250mL volumetric flask having uncertainty of ±0.02mL and ±0.1mL respectively. Calculate the volume of concentrated sulfuric acid 96% (±3) used and the uncertainty in 0.100M. dH2SO4 96 % = 1.84 (±0.05) g/mL FMH2SO4 = 98.079 g/mol b) If you want to prepare 1.00 L of buffer at pH 7.54 with a total phosphate concentration of 0.500 M, how many grams of each selected compounds below would you mix? Given that: H3PO4 (FM 98.00), NaH2PO4 (FM 119.98), Na2HPO4 (FM 141.96), and Na3PO4 (FM 163.94)? Ka1 = 7.1 x 10-3; Ka2 = 6.3 x 10-8; Ka3 = 4.5 x 10-13
Practice: uncertainty and relative uncertainty You prepared a 0.250M NH3 solution by diluting 8.45 (+±0.04)mL of 28.0 (±0.5)wt% NH3 (density = 0.899 ± 0.003)g/mL) up to %3D 500.0 (±0.2)mL. Find the uncertainty in 0.250 M. Consider the molar mass of NH3, 17.031g/mol, to have negligible uncertainty. hp
Internal standard (As , Cs ), analyte with known concentration (Ax , Cx ) In a chromatographic equipment, a solution containing 0.006727 X and 0.008331 M S give peak area of Ax= 2316 and As= 207. To analyze an unknown sample, 5.0mL of 0.008331M S was added to 5.0mL of X, and the mixture was diluted to 50.0mL. This mixture gave a chromatography spectrum with area Ax= 3206 and As= 200. Find Cx.
Please explain on how to this problem. Thank you!
In a chromatography experiment, a solution containing 0.083 7 M X and 0.066 6 M S gave peak areas of AX = 423 and AS 5 347. (Areas are measured in arbitrary units by the instrument.) To analyze the unknown, 10.0 mL of 0.146 M S were added to 10.0 mL of unknown, and the mixture was diluted to 25.0 mL in a volumetric flask. This mixture gave the chromatogram in Figure 5-8, with peak areas AX = 553 and AS = 582. Find the concentration of X in the unknown.
