Wet ashing involves heating a sample with a nitric acid solution to decompose organic material into ash. Dry ashing involves heating a sample in a furnace to completely combust organic material to ash without the use of acid. Both methods are used for preparing samples for further analysis, such as inorganic elemental analysis.

Which elements are likely to be lost by dry ashing?

Elements that are likely to be lost by dry ashing include volatile elements such as mercury, arsenic, and selenium. These elements can evaporate or sublime at the high temperatures used during dry ashing, leading to their loss from the sample.

How is a tropical wet climate similar to a tropical wet and dry climate how are they different?

Both tropical wet and tropical wet-and-dry climates are found near the equator and typically experience high temperatures year-round. The main difference is the amount of precipitation they receive: tropical wet climates have consistent rainfall throughout the year, while tropical wet-and-dry climates have distinct wet and dry seasons.


What countries are tropical wet and dry?

Countries with tropical wet and dry climates include India, Thailand, Mexico, Brazil, and Australia. These countries typically experience distinct wet and dry seasons throughout the year, with heavy rainfall during the wet season and drier conditions during the dry season.


How do you calculate dry density from weight of wet sediment?

To calculate dry density from the weight of wet sediment, you need to first determine the volume of the wet sediment. You can do this by dividing the weight of the wet sediment by the bulk density of the sediment. Once you have the volume of the wet sediment, you can then calculate the dry density by dividing the weight of the wet sediment by the volume of the wet sediment.
