1. Which laboratory instrument is primarily used to measure the acidity
or alkalinity of a solution?
A. Spectrophotometer
B. Centrifuge
C. pH meter
D. Calorimeter
Rationale: A pH meter directly measures hydrogen ion concentration,
determining the pH of a solution.
2. What is the chemical formula for sulfuric acid?
,A. HCl
B. HNO3
C. H2SO4
D. NaOH
Rationale: Sulfuric acid consists of two hydrogen atoms, one sulfur atom,
and four oxygen atoms.
3. Which safety document contains information about handling
hazardous chemicals?
A. Calibration Log
B. Production Schedule
C. Batch Record
D. Safety Data Sheet (SDS)
Rationale: SDS documents provide chemical hazard, handling, storage, and
emergency response information.
4. What type of bond involves the sharing of electrons between atoms?
A. Ionic bond
B. Metallic bond
C. Hydrogen bond
D. Covalent bond
,Rationale: Covalent bonds form when atoms share electrons to achieve
stable electron configurations.
5. Which unit is commonly used to express concentration in industrial
chemistry?
A. Newton
B. Pascal
C. Molarity
D. Joule
Rationale: Molarity expresses the number of moles of solute per liter of
solution.
6. What is the purpose of a catalyst in a chemical reaction?
A. Increase product mass
B. Lower pressure
C. Increase reaction rate without being consumed
D. Neutralize acids
Rationale: Catalysts accelerate reactions by lowering activation energy
while remaining chemically unchanged.
7. Which gas is commonly used in inert atmospheres during industrial
reactions?
, A. Oxygen
B. Chlorine
C. Carbon dioxide
D. Nitrogen
Rationale: Nitrogen is relatively nonreactive and helps prevent unwanted
oxidation or combustion.
8. What is the boiling point of water at standard atmospheric pressure?
A. 50°C
B. 75°C
C. 100°C
D. 125°C
Rationale: Pure water boils at 100°C under one atmosphere of pressure.
9. Which personal protective equipment protects the eyes from chemical
splashes?
A. Gloves
B. Hard hat
C. Ear plugs
D. Safety goggles
Rationale: Safety goggles provide sealed eye protection against hazardous
liquids and vapors.
