List the steps involved in gravimetric analysis.

• The steps involved in gravimetric analysis include: sample preparation, precipitation, filtration, washing, drying, and weighing.

• Heating, filtering, and titrating

• Dissolving, evaporating, and measuring

• Mixing, heating, cooling, and analyzing

In gravimetric analysis, what is the purpose of precipitation?

• To heat the solution to a higher temperature

• To separate the analyte from the solution in the form of a solid precipitate.

• To dissolve the analyte in the solution

• To measure the volume of the solution

What is the difference between gravimetric analysis and volumetric analysis?

• Gravimetric analysis measures the volume of a substance

• Gravimetric analysis measures the mass of a substance, while volumetric analysis measures the volume of a substance.

• Volumetric analysis measures the temperature of a substance

Explain the concept of gravimetric factor in gravimetric analysis.

• The gravimetric factor in gravimetric analysis refers to the ratio of the mass of the desired substance to the mass of the sample being analyzed. It is used to calculate the amount of the desired substance present in the sample.

• The gravimetric factor is the color of the desired substance in the sample

• The gravimetric factor is the volume of the sample being analyzed

• The gravimetric factor is the force of gravity acting on the sample
