You are given six numbered test tubes, 1–6. The test tubes contain 0.1 M solutions of the compounds Al(NO,)3 AgNO, Ba(NO3), Ca(NO3), CUSO, Zn(NO3), You test each of the unknowns with each of the given reagents. 6 M H,SO, 6M NH,ОH 6 M NAOH 6 M HCI For each trial, you take 5 drops of unknown and 2 drops of the reagent and mix them in a well plate. The data from your tests is recorded in the table. Identify each unknown solution. Unknown Unknown 1 Unknown 2 Unknown 3 Unknown 4 Unknown 5 6 white precipitate forms white white precipitate forms dark white bluish-white precipitate precipitate slowly forms NaOH then dissolves, forms then dissolves, forms brown precipitate colorless solution colorless solution precipitate white white HC1 precipitate no reaction bluish-green solution no reaction no reaction precipitate slowly forms white no H, SO, no reaction no reaction blue solution no reaction precipitate reaction bluish-white precipitate forms then dissolves, forms no reaction white precipitate forms white brown NH,OH then dissolves, forms white precipitate precipitate precipitate colorless solution dark blue solution
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Identify the unknown compounds (1-6) as Al(NO3)3, AgNO3, Ba(NO3)2, Ca(NO3)2, CuSO4, or Zn(NO3)2
