Listing 10 of 87 questions
Silver chloride, AgCl, is an insoluble salt and silver nitrate is a soluble salt. Silver chloride can be prepared by the reaction between aqueous silver nitrate and dilute hydrochloric acid. Describe the preparation of a pure, dry sample of silver chloride from aqueous silver nitrate and dilute hydrochloric acid. Write the ionic equation, including state symbols, for this reaction. Silver chloride decomposes in the presence of light to make silver and chlorine. What is the name of the type of reaction that requires light? Construct the equation for the decomposition of silver chloride. Silver nitrate can be prepared by reacting silver oxide with dilute nitric acid. Ag2O + 2HNO3 2AgNO3 + H2O Excess silver oxide is reacted with 30.0 cm3 of 0.150 mol / dm3 nitric acid. After purification the percentage yield of silver nitrate is 80.0%. Calculate the mass of silver nitrate prepared. Give your answer to three significant figures. [Mr: AgNO3 , 170] mass of silver nitrate g
