A 500 mL water sample was analyzed for solids concentrations. The sample was filtered through an ash-free 1.5 µm filter paper having a tare weight of 1.115 g. After drying at 105 °C for 24 h, the filter paper weighed 1.552 g. The filter paper was then placed in a crucible having a tare weight of 32.216 g and which was then placed in an ashing oven at 550 °C for 24 h. After cooling, the crucible weighed 32.521 g. A subsample consisting of 50 mL of the filtrate was placed in a crucible having a tare weight of 41.814 g. After drying (105 C for 24 hr), the crucible weighed 41.828 g, and after ashing (550 C for 24 hr) it weighed 41.820 g.

Required: Determine the following concentrations in mg/L: a. Total suspended solids (TSS) b. Fixed suspended solids (FSS) c. Volatile suspended solids (VSS) d. Total dissolved solids (TDS) e. Fixed dissolved solids (FDS) f. Volatile dissolved solids (VDS) g. Total solids (TS) h. Total volatile solids (TVS) i. Total fixed solids (TFS)

Primary clarifier effluent was analyzed for solids content by an analytical laboratory. A 250-mL sample of the effluent was filtered through a laboratory (1 micrometer) filter. A 241-mL sample of the filtrate contained 89 mg of salts as dissolved solids (Residue 1). Solid residue from the filtration was dried overnight at 105 deg C and weighed 37 mg (Residue 2). What were the concentrations of total dissolved solids, total suspended solids, and total solids in the primary clarifier effluent? Water...

A 2.67 g sample of plant tissue was analyzed for its zinc content. 23.25 ml of a standardized 0.010 Molar solution of EDTA was used to titrate the sample (by complexing with the zinc ions), determine the mass of zinc in the sample and express the value as;a. ppm zinc?b. ppb zinc?c. What mass of zinc product would form if the zinc (2+) ions were instead allowed to precipitate as zinc phosphate?3Zn2+(aq) + 2PO43-(aq)Zn3(PO4)2(s)

A 25.0-mL sample of lambic (a sour Belgian beer) was analyzed for its acetic acid content by an electrochemical method. The pure sample registered a signal of 2.55 mA. A standard solution of 0.500 mL of 0.109 M acetic acid was added, and the signal increased to 2.98 mA. What is the acetic acid concentration in the original lambic sample?
