Hydrochloric acid and Sodium thiosulfate produce a precipitate. Watch this video and answer how does INCREASING the concentration of reactants affect the rate of reaction?
a
It increased the rate of the reaction
b
It did not affect the rate of reaction
c
It slowed down the rate of reaction
a. It increased the rate of the reaction
To determine how increasing the concentration of reactants affects the rate of reaction in the reaction between hydrochloric acid and sodium thiosulfate, you will need to watch the video provided. Based on the observations in the video, you can then choose the most appropriate answer from the options given. As an AI text-based model, I am unable to watch videos. Therefore, I cannot provide a specific answer to this question. Please watch the video and refer to the observations made in the video to determine the correct answer.
To find the answer to this question, you can observe the experiment shown in the video. Here's how you can do it:
Step 1: Watch the video. Pay attention to the reaction between hydrochloric acid and sodium thiosulfate. Note any changes that occur during the experiment.
Step 2: Observe the concentration of the reactants. Take note of how the concentration of hydrochloric acid and sodium thiosulfate is adjusted throughout the video.
Step 3: Analyze the rate of reaction. Observe the time it takes for a precipitate to form during each concentration change of the reactants.
Step 4: Compare the observations. Compare the rate of reaction for each concentration change. Determine whether the rate increased, remained the same, or slowed down.
Step 5: Answer the question. Based on your observations, select the option that best describes the effect of increasing the concentration of reactants on the rate of reaction.
By following these steps, you will be able to gather the necessary information from the video and make an informed decision about how increasing the concentration of reactants affects the rate of reaction.
