Which apparatus is used to make a large amount of chemicals?
A chemical plant is used to make a large amount of chemicals. It is used to make chemicals so that we can use them in what ever we need to have them made into. Which apparatus is used to transfer small amounts of liquid chemicals?
Is it safe to mix certain chemicals?
Improperly mixed chemicals cause a shocking number of fires, explosions, and injuries in laboratories, businesses, and homes each year. A new open sourcecomputer program called ChemStor developed by engineers at the University of California, Riverside, can prevent these dangerous situations by telling users if it is unsafe to mix certain chemicals.
How does chemstor work?
ChemStor draws from an Environmental Protection Agency library of 9,800 chemicals, organized into reactivity groups. It then builds a chemical interaction graph based on the reactivity groups and computes the smallest number of colors that will color the graph such that no two chemicals that can interact also share the same color.

What is used for transferring small amounts of solid chemicals?
A spatula is the correct tool for transferring solids from one container to another. Always check that the spatula is clean and do not use the same spatula for different solids, unless cleaned in water and dried. Spatulas come in various shapes and sizes so beware of instructions that simply say “use a spatula-full”.

3) Spatula/Scoop-used to take out or transfer small quantities of solid chemicals. Ideal for transferring from small bottles.
How do you transfer chemicals?
Many solid chemicals can be easily transferred by tipping the bottle and slowly rotating the bottle back and forth. Don't tip the bottle up high and let the contents pour out. If a spatula is provided at the reagent bottle, you may use it. Never use your own spatula.

What is a beaker used for?
Beaker is mainly used for holding liquids in the laboratory, but it can be used for a variety of other purposes such as measuring liquids or as a collecting vessel in acid-base titration. It comes in different sizes and it can be made of glass or plastic.
Why do mortar and pestle come together?
Mortal and pestle come together; they are used to grind solid chemical into powder. This usually occur when one want to increase the surface area of a solid substance in order to speed up the rate of chemical reaction. Mortal and pestle are usually made of ceramic.
Why is gauze used in the laboratory?
