Conclusion: 1)What is the answer to the problem question? 2)Was your hypothesis correct? Defend your answer with the lab results. 3)What were the sources of error while performing the lab? 4)What could be done differently next time in the experiment? 5)What chemistry did you learn? Answer all questions in one paragraph.

Problem: What problem will this lab answer? This must be in question format. Hypothesis Write this in an if... then statement. Be sure the independent and dependent variables are in the correct location. Method: Briefly describe what you did in the lab (the procedure.) Include chemicals used and any special equipment as you describe what you did. Results: 1) What type of data did you collect? 2) Summarize the chemistry results of the lab. 3) What did you observe? Was there something that you found interesting or Unusual about the experiment? How does temperature affect the rate of reaction between hydrochloric acid and sodium thiosulfate? If the temperature of the reaction mixture is increased, then the rate of reaction between hydrochloric acid and sodium thiosulfate will increase, causing the reaction time to decrease. In this lab, | looked at how temperature affects how quickly reactions happen. | mixed hydrochloric acid (HCI) with sodium thiosulfate (Na2S203) using a beaker, test tubes, a thermometer, and a stopwatch. First, | put sodium thiosulfate in a test tube. Then, | added a certain amount of hydrochloric acid to a beaker. To see how fast the reaction was, | placed the beaker on paper with a symbol on it. | heated the solution to different temperatures with a hot water bath, keeping track with the thermometer. Right after mixing the solutions, | used a stopwatch to time how long it took for the symbol to disappear, showing that the reaction was happening. | did this three times at different temperatures to see how higher temperatures change the reaction speed. In this lab, | measured how long it takes for hydrochloric acid and sodium thiosulfate to react at different temperatures. | found that when the temperature went up, the reaction happen faster. This matches the idea that higher temperatures give more energy to the molecules, making them collide more often and effectively. It was interesting to see how quickly the reaction made the solution cloudy
