What is the structural formula of benzoic acid?
C7H6O2Benzoic acid / Formula
Benzoic acid is a white (or colorless) solid with the formula C6H5CO2H. It is the simplest aromatic carboxylic acid.
What is the enthalpy of solution of benzoic acid?
With the aid of the Van’t Hoff equation, the enthalpy of solution of benzoic acid at those temperatures was determined as 10.82 KJ. This compares well with the value of 10.27KJ found in the literature.
What is the molar enthalpy of combustion of benzoic acid?
The enthalpy of combustion of benzoic acid ( C 6 H 5 C O O H ) is commonly used as the standard for calibrating constant-volume bomb calorimeters; its value has been accurately determined to be -3226.7 kJ/mol.
What is the standard molar enthalpy of combustion ∆ H comb per mole of benzoic acid?
The combustion of benzoic acid in a bomb calorimeter releases 26.38 kJ of heat per gram (i.e., its ΔHcomb = −26.38 kJ/g).
What is the energy of benzoic acid?
The internal energy of combustion of benzoic acid is -3251 kJ mol-1.
What is the functional group of benzoic acid?
carboxyl acid
Benzoic acid is a benzene-based carboxyl acid, commonly used as a food preserver. It is composed of two functional groups, a benzene, or aromatic, ring, and a carboxyl group.
Is the heat of solution of benzoic acid endothermic or exothermic?
It was found that H is -243,7J/kg. Since H has a negative value, it indicates that the dissolution of benzoic acid is an exothermic process.
What is GCV of benzoic acid?
Due to its constant value it is the ideal substance for calibration in bomb calorimeters. For this purpose we press the powdery substance into tablets of approximately 0.5 grams and 1.0 grams, with a calorific value of approximately 26.454KJ/g.
How benzoic acid is formed?
Benzoic acid is produced commercially by partial oxidation of toluene with oxygen. The process is catalyzed by cobalt or manganese naphthenates. The process uses abundant materials, and proceeds in high yield.
What is the Iupac name of C6H5COOH?
Benzoic acid | C6H5COOH – PubChem.
Which indicator is used in determination of heat of solution of benzoic acid *?
Caution, above 70°C benzoic acid may be decompose. 2- Use the pipette to transfer 10 ml from the filtrate to the conical flask, and titrate with the standard (0.1N) NaOH solution, using phenol phthalein as the indicator. 3- Repeat step 2 at different temperature (30)°C.
