Keeping It in the Family

Solution containing silver ions (silver nitrate) will be mixed with salts (potassium chloride, potassium bromide, potassium iodide), drop wise, in various proportions to determine the properties of the precipitate formed. Students will analyze the proportion that provides the best precipitate. Using prior knowledge of writing balanced chemical equations, students should write balanced chemical equations and compare the equation to their data (theoretical vs. actual). Lastly, students will determine the type of reaction that is the focus of this lab (double displacement). When discussing theoretical vs. actual, can focus on sources of error.
