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 slowed down the rate of reaction
b
It increased the rate of the reaction
c
It did not affect the rate of reaction
b) 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, we need to watch the video provided. Unfortunately, as an AI text-based bot, I am unable to watch videos. However, based on general chemical knowledge, I can explain the expected effects of increasing reactant concentration on the rate of reaction.
Typically, increasing the concentration of reactants leads to an increase in the rate of reaction. This is because a higher concentration of reactants provides more particles available to collide with each other, leading to more frequent successful collisions and thus an increased reaction rate. Therefore, in this case, it is likely that increasing the concentration of hydrochloric acid and sodium thiosulfate would lead to an increased rate of reaction.
However, without watching the video, we cannot confirm the specific outcome. I recommend watching the video to observe the actual experimental results and find out whether increasing the concentration of reactants affected the rate of reaction.
To determine how increasing the concentration of reactants affects the rate of reaction in the given reaction between hydrochloric acid and sodium thiosulfate, you can follow these steps:
1. Watch the provided video to observe the reaction between hydrochloric acid and sodium thiosulfate.
2. Pay attention to the changes occurring during the reaction, particularly the formation of a precipitate.
3. Note the concentration of the reactants at the beginning of the reaction.
4. Now, consider how increasing the concentration of reactants affects the rate of reaction:
a. If increasing the concentration of reactants leads to a faster reaction and quicker formation of the precipitate, then select option b - "It increased the rate of the reaction."
b. If increasing the concentration of reactants causes the reaction to take longer, resulting in a slower formation of the precipitate, then select option a - "It slowed down the rate of the reaction."
c. If increasing the concentration of reactants has no noticeable effect on the rate of reaction and there is no significant change in the time taken for the formation of the precipitate, then select option c - "It did not affect the rate of reaction."
5. Based on your observations and analysis, select the option that best represents the effect of increasing the concentration of reactants on the rate of reaction in the given video.
Please note that without watching the video and directly analyzing the reaction, it is challenging to provide a precise answer.
