A titration was performed on 10 ml of unknown weak acid. NaOH was titrated with it. The NaOH concentration was 0.09445. The second equivalence point was at 18.85 and the first at 9.42. If the acid is 8.10279 g/L what is the molar mass?
If a 1,2-diol is subjected to a periodic acid test, a white solid will form when silver nitrate is added. What is the identity of the white solid?

the barometric pressure in a cavern was measured using a mercury barometer. a value of 28.2 inches of hg was obtained.
Explain why adding excess of sulfuric acid to the solution from which crystallization of alum is to take place helps to suppress the hydrolysis of Al3+
Require to apply to neutralize the acidity that concluded from nitrification and determine how much CaCO 3
A solid mixture contains MgCl2 and NaCl. When 0.5000 g of this solid is dissolved in enough water to form 1.000 L of solution, the osmotic pressure at 25°C
Precipitation titration of a 25.0mL of AgNO3 aliquot analyte with 0.0230 M KCl requires 1.50mL of the titration to reach equivalence. Find out the pAg+ at the following points of the titration and sketch the resulting pAg+ vs mLs of KCl added. Ksp..
