the non-metal that is responsible for the colour produced in the flame test for that salt. How can you be sure your answer is correct? Metal is responsible for the colour produced in the flame test for that salt. All salts contain chloride ion. If non-metal ion‚ chloride‚ is responsible for the colour‚ all colour produced will be the same. 3. Why do the chemicals have to be heated in the flame before the coloured light is emitted? For the coloured light to be emitted‚ the electrons have to get

reaction. The reaction begins by first converting the m-toluic carboxylic acid into an acyl chlorosulfite through a reaction using thionyl chloride. The carboxylic acid is converted into an acyl chloride because the acyl chloride is more reactive. In this step‚ hydrochloric acid is formed from a hydrogen on the carboxylic acid and a chlorine from the thionyl chloride atoms binding together. A chlorine atom then attaches itself to a double bonded oxygen on the acyl chlorosulfite‚ kicking the double bonded

boiling points‚ and do not conduct electricity. Since electrons are shared in covalent bonds‚ they have slightly different properties than ionic-bonded compounds. Based on these properties‚ the best compound for your ceramic fixative would be sodium chloride (NaCl)‚ because it has an ionic bond‚ has a high melting and boiling point‚ is electrically conductive‚ dries white‚ and can dissolve in water but not in alcohol. When we conducted this experiment‚ we used distilled water to test if the compounds

(6) Observe the change in colour of the Bunsen burners flame and record the observations as you go. (7) As long as you clean the wire as directed in step 3-4 you can proceed into testing the other metal salts.

aqueous Silver nitrate is added to separate aqueous solutions of Sodium chloride and sodium Bromide When the solution of sodium chloride is added to the aqueous solution of silver nitrate it would be displaced by the sodium chloride to form a silver chloride and sodium nitrate. This would happen because the chloride is a more reactive element and displaces the weaker element‚ which is the silver. The silver chloride is insoluble and this would form a white precipitate.

The different salts included Potassium chloride‚ Calcium chloride‚ Strontium chloride‚ Lithium chloride‚ Copper II chloride‚ Sodium Chloride‚ and Barium Chloride. Burning a pinch of each salt separately by holding a nichrome wire over a Bunsen burner‚ we found that each salt emitted a different color of light. For example‚ Potassium Chloride burnt a bright pink flame when burned‚ while Calcium burnt orange. No color was truly identical. What

Chloride: Chloride is an essential electrolyte mineral. Chloride is the ionic form of chlorine. It is the main anion (Cl-) in the ECF‚ which occurs mostly in association with sodium. Chloride moves passively across membranes through channels and so also associates with potassium inside cells6. In the stomach‚ the chloride ion is part of hydrochloric acid‚ which maintains the strong acidity of the gastric juice6
