Which of the following statements about empirical formulas is incorrect.

. A An empirical formula represents a molecule. In the same way the strength of a base can be found with the help of a standard solution of an acid which is known as alkalimetry. Molar mass of NaOH is the sum total of individual elements molar mass 23161 40gmol.

The strength of an acid can be determined using a standard solution of a base. A place for chemistry enthusiasts and professionals alike. A 224 B 133 C 267 D 345 E none of the above.

C An empirical formula must be multiplied by. A primary standard is any material that can be exactly weighed out in pure form such as oxalic acid so that the number of moles present can be estimated reliably by the measured weight and the known molar mass. What is the mass percent of carbon in oxalic acid H2C2O4.

Formic acid is a colorless liquid having a pungent penetrating odor at room temperature comparable to the related acetic acidFormic acid is about ten times stronger than acetic acid. This process is called acidimetry. Main standards need not necessarily be the standard solutions used in the acid-base titration.

Check out a buret from the. Chemistry tools periodic table unit converters and more. Density of Aqueous Solutions of some Inorganic Substances - Changes in density of aqueous solutions with changes in concentration at 20C.

Molegiven massmolar mass from this basic formula given mass molemolar mass. Density of acetic acid citric acid formic acid D-lactic acid oxalic acid and trichloroacetic acid in water is plotted as function of wt molkg water and moll solution. From this result we can.

The reaction between NaOH and KHP molar mass 20423 gmole is as follows. B An empirical formula gives the smallest whole number ratio of each type of atom in a molecule. NaOH HOOC-C6H4-COOK Æ NaOOC-C6H4-COOK H2O By measuring the volume of the 02M NaOH solution dispensed from the buret that is necessary to react completely with a weighed sample of KHP the exact concentration of NaOH solution is calculated.

It is miscible with water and most polar organic solvents and is somewhat soluble in hydrocarbonsIn hydrocarbons and in the vapor phase it consists of hydrogen-bonded dimers.
