In each box of the well plate, a pipette was used to add three drops of each of the specified chemicals. For example, well a contained three drops of GAG+ and three drops of CHIC; The pipette was rinsed in soapy and plain water to reuse them for each new solution. The new substance that was produced when the solutions were mixed was then observed. Each precipitate that formed was described. Terms such as milky, grainy, cloudy or gelatinous were used. A combination that did not form a precipitate was noted by writing “no reaction visible. The well plate was then thoroughly rinsed in the sink.
All pipettes were rinsed using a beaker of soapy water and plain water; many other clean up procedures were then followed. Safety precautions were taken by wearing goggles and gloves at all times, care being taken when handling chemicals with pipettes and avoiding contact with the skin and clothing. After experimenting it resulted that CHIC- mixed with Gag+ was a milky white substance that looked like paint. CHIC- mixed with Pub+ was gelatinous; mixed with Ca+ was gelatinous and cloudy; mixed tit Fee+ was grainy; mixed with MGM+ was cloudy and last but not least mixed with Cue+ was blue and cloudy.
Crater- mixed with Gag+ was a reddish brown substance; when mixed with Pub+ and Fee+ both substances were gelatinous; with Ca+ was a clear yellow substance; with MGM+ was yellow and with Cue+ was grainy. SASS- mixed with Gag+ was cloudy; with Pub+ was milky and white; the substance was clear when It was mixed with Ca+; when mixed with Fee+ it was a brown color and clear and lastly when mixed with MGM+ and mixed with Cue+ they both came out as clear substances. Questions: 1. What Is a precipitate?
A precipitate is the solid that forms when two chemicals are mixed together. 2. Describe how an ionic compound is formed. 3. Describe the properties of ionic compounds. 4. Write the formulas and names of the Ionic compounds produced In the lab (a-r) conclusion: To conclude this lab, the observations of the formation of compounds were made and the names and formulas of ionic compounds were written. The recognition and description of precipitates was also made. Ionic compounds By distances When ionic compounds are dissolved in water, they break apart into ions.
In this lab ions will remain dissolved and uncombined in the solution even when they are mixed with other ions. When other ions are mixed, they form compounds that appear as each of the specified chemicals. For example, well a contained three drops of GAG+ and three drops of CHIC- The pipette was rinsed in soapy and plain water to reuse with Gag+ was cloudy; with Pub+ was milky and white; the substance was clear when it 1.
