Question

Which technique produces a compound which is not soluble in water?

• A. Conductivity
• B. Calorimetry
• C. Precipitation
• D. Spectrophotometry

Answer 1

The correct option is C Precipitation

A reaction occurs when you mix two aqueous solutions. This is when you will find out whether a precipitate will form or not. A precipitate forms if the product of the reaction is insoluble in water.

Precipitation occurs when cations and anions in the aqueous solution combine to form an insoluble ionic solid called a precipitate.

Conductivity is the property to conduct electricity, calorimetry is the process of measuring the heat of chemical reactions and spectrophotometry is the measurement of reflection or transmission properties of the material as a function of wavelength.

Since precipitation produces a compound which is not soluble in water, the correct answer is the option (C).
