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)

Loss 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.

Yes: dry residue may be the residue obtained after drying at 110-115 0C and residue after ignition is obtained at a higher temperature, up to 1 000 0C.

WHAT OR DEFINE constant weight?

Constant weight refers to maintaining a stable and consistent body weight over a period of time without significant fluctuations. This means that the person's weight remains relatively steady without significant changes in either direction (gain or loss). It often indicates a balance between caloric intake and energy expenditure.

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 is the difference between rasins and sultanas?

The main difference between raisins and sultanas is the type of grape used and the drying process. Raisins are made from red or green grapes, while sultanas are made from seedless green grapes. Raisins are typically dried in the sun or mechanically dried, while sultanas are dried using a special drying process that involves dipping the grapes in a solution to speed up the drying. In terms of taste, sultanas are generally sweeter and juicier than raisins.

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.
