Given that the equivalence point volume from the second derivative plot is 7.3429, how many grams of salicylic acid (138.121 g/mol) was synthesized? To determine the yield of the hydrolysis reaction, potentiometric titration was done. NaOH was used as the titrant, and three trials of standardization with KHP yields a titrant concentration of 0.0427 M.
I made some titrations and the calculated molarity of HCI was 0.096, 0.097 and 0.098. The nomical concentrsrion of HCl is 0.1. How can I explain my results by comparing it to the nominal concentration if my confidence intervals don't include the nominal concentration?
0.1 g of the mixture of na2so4 and k2so4 is taken and 100 ml of solution is prepared. 10 ml of this prepared solution is placed in a beaker and some distilled water is added. A mass of 15.5 mg is obtained by precipitation with Bacl2 at PH=5, then filtering and bringing to a constant weight at 800 °C. Calculate the percentages of Na2so4 and K2so4 in the mixture accordingly.
Phenylacetic acid (C6H5CH2CO2H) is a weak monoprotic acid with Ka=4.90x10-5. what is the pH that results by mixing 2.56 g of phenylacetic acid with 1.59 g of potassium phenylacetate and diluting to 250.0 mL?

A 1.0 g sample containing urea was dissolved in water and diluted in a 100.00 mL volumetric flask. 20.00 mL aliquot was mixed with 30.00 mL water and subjected to digestion with concentrated H2SO4. The ammonia produced is collected in 30.00 mL of 0.0500 M HCl and the excess acid is back titrated with 0.0500 M NaOH, requiring 6.80 mL. Calculate the weight percent urea [(NH2)2CO, FW=60.06 g/mol] in the sample.

A sample may contain NaOH, NazCO3 and NaHCO3, alone or in some combination, along with inert material. A samplewitha mass of 857.6 mgwas dissolved and titrated with0.1163 M HCI. The volume of HCl used from 0 to methyl red endpoint (Phenolphthalein endpoint was not monitored here) was found to be 36.54 mL. Another 228.8 mg portion of the sample was titrated to the phenolphthalein endpoint and 10.82 mL was used up for this titration. a. What is the composition of the sample? b. Calculate the percentage of each of the component present.
