im no expert but loss on drying refers to weight of mass after you dried something and then take that amount away from the pre died weight (so you have to know the initial weight) for residue on ignition are we still talking weight ? if so fire up the dry matter and then weigh wat you got left buddy
Loss on drying means at a define temp.how much volatile matter driven off form your sample means after ending the test you will get the sample without moisture and volatile matter but in residue on ignetion all part of organic matter will removed and only inorganic matter will present because we are finding how much inorganic impurity present in your sample (Dhiraj K.Thakur Abbott Healthcare)

MaxineLoss on drying is the measure of the moisture content in a sample, typically determined by heating the sample to drive off moisture. Residue on ignition is the measure of the inorganic materials present in a sample after heating it to a high temperature to burn off all organic matter.

What happen if you incomplete drying of the PbCrO4 residue prior to final weighing in experiment?
If the PbCrO4 residue is not completely dried before final weighing, it will contain residual moisture which can lead to an inaccurate measurement of the compound's weight. This can affect the reliability and precision of the experimental results. It is important to ensure that the residue is completely dry to obtain accurate and reproducible measurements.
What processes is not a physical change drying wet clothes cutting snowflakes out of paper light a match from a matchbook?
Ignition of a match is a chemical process.
What is the difference between drying agent and dehydrating agent?
A drying agent is a substance used to remove water or moisture from a material, while a dehydrating agent is a substance used to remove water molecules from a compound by chemical means. In general, drying agents are used for physical removal of water, while dehydrating agents are used for chemical reactions that result in water removal.
What is difference between evaporation and drying?
Evaporation is a natural process where a liquid turns into vapor, usually due to heat, while drying refers to the removal of moisture from a substance using methods such as air circulation, heat, or absorbent materials. Evaporation can happen without external intervention, while drying typically requires some form of action to remove the moisture.
What is the difference between crystallization and drying?
It's a very Nice question being asked..I am trying to give my thought on it ..hope it would help you out..In both Crystallization and drying, the solute has to be separated out from its solvent (generally water) but the difference is, in former case the solute attains a pure solid state having definite shape, pattern or in other words molecules are aligned in a particular pattern but in later case the solute is having only solid shape (not necessarily having regular pattern)
