Experiment 5 ionic reactions

All reactions will be performed in the well plate. Add about 2mL of each of the two reagents. The final form of the equation would be: Sodium phosphate solution will react with calcium chloride solution to form a white precipitate.

Place 2 drops of copper II nitrate into seven of the B wells. Do not perform reactions at the main dispensing hood. If the precipitates are allowed to dry they are much harder to remove. Also, most of these chemicals are toxic by ingestion. Bubbles of gas are formed when an aqueous solution of sodium carbonate reacts with an aqueous solution of hydrochloric acid.

Which cations generally do not form precipitates? A white precipitate is formed when solutions of silver nitrate and sodium chloride are mixed.

Also write the names of all reactants and products present in the balanced equations. When a salt dissolves in water, it separates into its constituent cations and anions. Gas Forming Reactions Some reactions can be classified as more than one of the reaction types listed above, and also may be called single-replacement or double-replacement reactions.

Which anions generally form precipitates? It is not necessary to measure the volumes of the reagents. As you record the results of each reaction in your laboratory notebook, be sure to include the test tube number.

They do not form precipitates. A salt is a compound that consists of a positive ion, called a cation, and a negative ion, called an anion.

Gently stir the ash with a glass rod and describe the appearance of the ash in your laboratory notebook. Bubbles of gas are produced when a solution of potassium hydrogen carbonate potassium bicarbonate reacts with a sulfuric acid solution. Place 2 drops of sodium sulfate solution into five vertical wells under 3.

Place 2 drops of nickel II nitrate into seven of the E wells. Be sure to use the solubility rules to determine the physical states of the products. Determine if any of the new compounds are insoluble using the solubility rules: In an acidic solution, litmus paper is red.

Place 2 drops of sodium hydroxide solution into five vertical wells under 7. Sodium bicarbonate and dilute sulfuric acid Pour about 2mL of aqueous sodium bicarbonate into an evaporating dish, not a test tube.Experiment 5: DOUBLE DISPLACEMENT REACTIONS Purpose: To observe and record the results when two ionic solutions are mixed.

To practice writing molecular, total ionic, and net ionic reactions. Background Information: A double displacement, or metathesis, reaction occurs when an. CHEM Experiment 5 2 Double replacement reactions (also called “double displacement” or “exchange” or “metathesis” reactions) have the general form AX + BY BX + AY Double replacement reactions typically form a product that is either molecular or ionic.

Revised 1/08, RJE. Ionic Compounds #2. Precipitation. The goal of this experiment is to help students understand precipitation reactions involving ionic compounds.

Ionic Reactions Lab. Chem Lab 5: Ionic Reactions Submitted by Abstract: The purpose of this experiment is to work with aqueous solutions of ionic substances.


Aqueous solutions are those solutions in which water is the solvent. When ionic substances are dissolved in water, the ions separate and become surrounded by water molecules.

The focus of this experiment is on precipitates. 1 Experiment In this experiment you will study ionic reactions in aqueous solutions. The mixing of ions may result in the precipitation of an insoluble compound.

The goal of this experiment is to study the nature of ionic reactions, write balanced equations, and to write net ionic equations for precipitation reactions.

Based on the solubility rules my results proved accurate.
