The laboratory aid that is used to transfer liquid from a wide-mouth container to a small-mouth container is the funnel. It is shaped like an inverted cone, with an extension of a small tube where the liquid passes. The filter paper is shaped into a cone and inserted to the funnel. The funnel allows you to transfer the liquid without spilling. In filtration, you separate the solid precipitate from the liquid filtrate. It depends on you which one of these you would keep. If you want to keep the filtrate, then the funnel is an efficient way to use if you don't want any of the filtrate to go to waste.
Law of Definite Proportions states that a compound is composed of the same ratio of elements present. The formation of water has a reaction:
H2 + 1/2 O2 = H2O
The limiting reactant would be the element with the least ratio of molar mass to stoichiometric coefficient, and that would be H2, not O2.
Answer:
Borax bead test
Explanation:
Another test that can be used to identify colored ions in a specific compound such as salt is called "Borax bead test".
This test involves use of a clear glassy bead of borax that is joined together in a wire loop which is going to be involved in chemical reaction with the salts of certain metals.
This reaction will produce colors that we can use to identify the exact metal ions that are present.
