When the solution of sodium carbonate is added to the solution of calcium chloride, a precipitate is formed. a. What is the colour of the precipitate formed? b. Name the precipitate. c. What is the type of the chemical reaction?

Which of the following is formed when Sodium hydroxide reacts with hydrochloric acid?

Apparatus: Two plastic bottles, measuring cylinder, thermometer, etc Chemicals: Potassium nitrate, sodium hydroxide, water, etc. (Sodium hydroxide being corrosive, handle it carefully in presence of teacher.) Procedure: Take I 00 mL water in each of the two plastic bottles. Plastic being insulator of heat, the dissipation of heat can be prevented. Note the temperature of water in the bottles. Put 5 g potassium nitrate (KNO_3) in the bottle and shake well. Note the temperature of the solution formed. Put 5 g sodium hydroxide (NaOH) in the other bottle. Shake the bottle well. Note the temperature. In the first bottle, the process of dissolution of potassium nitrate took place while in the second bottle, the process of dissolution of sodium hydroxide took place As per your observation which one is exothermic process and which is an endothermic process?

Apparatus: Test tube, conical flask, balance, etc. Chemicals: Sodium chloride and silver nitrate. Procedure: i. Take sodium chloride solution in a conical flask and silver nitrate solution in a test tube. ii. Tie a thread to the test tube and insert it carefully into the conical flask. Make the conical flask air tight by fitting a rubber cork. iii. Weigh the conical flask with the help of a balance. iv. Now tilt the conical flask and mix the solution present in the test tube with the solution in the conical flask. v. Weigh the conical flask again. Did any insoluble substance form?
