You have a beaker full of H2SO4 with electrodes dipped in it which are attached to a lightbulb (and the lightbulb is on). You add a dilute solution and the bulb grows dim. Which of the following could have been added: Ba(OH)2, NaNO3, K2SO4, and/or Ca(NO3)2. Please explain your reasoning.

Answer #1

The chemical equations are as shown.

As can be seen from above reactions, when barium hydroxide is added to solution, no ions are formed. In this reaction sulphuric acid (which conducts electricity due to ionisation) is consumed and hence, there is decrease in the electrical conduction due to addition of barium hydroxide. Hence, the bulb will glow dim.

In all other cases, since the products ionize, there will not be any decrease in the electrical conductivity. Hence, the bulb will not glow dim.

Part A To what volume should you dilute 20 mL of a 12.0 M H2SO4 solution to obtain a 0.130 M H2SO4 solution? Express your answer using two significant figures. Part A Classify the following reactions: HCl(aq)+NaOH(aq)→NaCl(aq)+H2O(l) Ba(OH)2(aq)+ZnCl2(aq)→BaCl2(aq)+Zn(OH)2(s) 2AgNO3(aq)+Mg(s)→Mg(NO3)2(aq)+2Ag(s) Drag the appropriate items to their respective bins.

In this experiment you will construct a smal electrolytic cell. Then using indicators you will determine the products fromed at the anode and the cathode druing several different electrolysis experiments. About the experiment: in the first part of this experiment you will construct a small scale chlorine production plant. it is a miniature of the real, large scale process used for production of chlorine by the electrolysis of sodium chloride or brine (procedure written by Dr. Stephen thompson, CSU, CO)...

Chemical Reactions Types and Their Equations Making Heat with Chemical Reactions Have you ever wondered how an instant heat pack works? A disposable heat pack works by a chemical reaction that combines iron in the package with oxygen from the air when the outer packaging is removed producing iron oxide. You have probably seen the product of this reaction in what is commonly called rust. The reaction releases heat, which allows the pack to reach a sufficient temperature that is...

Place a piece of copper wire in a weighing paper, determine the mass of the wire and place it in the centrifuge tube. The copper wire should weigh less than 0.0200 grams. 3. In a fume hood, add seven drops of concentrated nitric acid to the reaction tube so that the copper metal dissolves completely. Describe your observations in the lab report. (Caution, Concentrated nitric...
