Ionic reaction lab report

One possible source of error was small air bubbles trapped in the solution that were unnoticed before the solution was tested, which would make it seem as if gas had been produced from the reaction. J Simpson from a lab originally by S.

Other compounds follow these solubility rules, but they contain certain exceptions.

A physical property is any change that does not involve the chemical makeup of a substance at all. Remember, a reaction may be indicated by the formation of a precipitate, color change, or the formation of gas. It is also possible that some of the solutions did react, but the reaction was not visible or was difficult to see.

ionic reactions in aqueous solutions lab answers

Most cations and anions have an exception that prevents them from being either insoluble or soluble and causes the to be the opposite. Bookmark the permalink. If both products are aqueous, the reaction doesn't take place because the 'soup' of ions remains a 'soup' where no ions are attracted to one another.

At different stages of the cycle, copper was present in different forms.

Aqueous solutions are solutions that water is solvent. Some compounds containing certain elements or polyatomic ions are always soluable, such as compounds which contain ammonium or nitrate. Before the compounds dissolve and the ions separate, the equation is called the molecular equation. When an ionic or polar substance is placed in water, the water molecules are attracted to the charges: the oxygen has a slight negative charge and is attracted to the cations, while the hydrogen, with its slight positive charge, is attracted to the anions. For example, hydrochloric acid reacts with sodium hydroxide to produce water and sodium chloride, but sodium chloride is soluable and water is clear, therefore making the reaction unable to be seen. Discussion of Theory: The lab tested many different types of chemicals, and the reactions were a way to test the solubility rules by seeing which compounds reacted. If both products are aqueous, the reaction doesn't take place because the 'soup' of ions remains a 'soup' where no ions are attracted to one another.

Record the well numbers of the precipitates you chose for your equations. Because our unknown compound did not dissolve in the substances, but quickly dissolved in water, this lead us to believe that our compound was not an organic acid or base.
