Suguna Foods Chemist Interview Questions, Process, and Tips

The density of H2SO4 and HNO3 varies depending on the concentration.

• The density of H2SO4 and HNO3 can be calculated using the formula: density = mass/volume.

• The density of H2SO4 and HNO3 increases with increasing concentration.

• The density of H2SO4 and HNO3 at standard conditions (concentration of 1 M) is approximately 1.84 g/mL and 1.41 g/mL, respectively.

pH is a measure of the acidity or alkalinity of a solution. It indicates the concentration of hydrogen ions in the solution.

• pH scale ranges from 0 to 14, with 7 being neutral.

• A pH value below 7 indicates acidity, with lower values being more acidic.

• A pH value above 7 indicates alkalinity, with higher values being more alkaline.

• Each unit change in pH represents a tenfold change in acidity or alkalinity.

• Examples: Lemon j...read more

The molecular weight of H2SO4 is 98.09 g/mol.

• The molecular weight of H2SO4 can be calculated by adding up the atomic weights of its constituent elements.

• H2SO4 consists of 2 hydrogen atoms, 1 sulfur atom, and 4 oxygen atoms.

• The atomic weights of hydrogen, sulfur, and oxygen are 1.008 g/mol, 32.06 g/mol, and 16.00 g/mol respectively.

• Multiplying the atomic weights by the number of atoms and summing them gives the molecula

Ethanol and methanol are two common types of alcohol. Ethanol has the formula C2H5OH, while methanol has the formula CH3OH.

• Ethanol formula: C2H5OH

• Methanol formula: CH3OH

Normality, molality, and molarity are different ways to express the concentration of a solution.

• Normality is the concentration of a solution expressed in equivalents per liter.

• Molality is the concentration of a solution expressed in moles of solute per kilogram of solvent.

• Molarity is the concentration of a solution expressed in moles of solute per liter of solution.

• Normality is used in acid-base reactions, while molali...read more
