Why does it take longer for strong acids to react than weak acids?
I don't know that it does. Do you have an example?
In my last lab, we timed how fast hydrochloric acid, acetic acid, and water react with baking soda. Our results showed that water did not react, acetic acid did it in 40 seconds, and HCL was 105 seconds. I do not know whether our data is wrong or not.
Were the concentrations different? Was the soda in solution or dry? Did you measure the volume of gas produced? Was the time what it took to ???what? stop fizzing? That is, how did you know when the reaction stopped? That is, what did you time?
The soda was dry, the concentrations were the same, we did not measure volume of gas produced, yes it was the time to stop fizzing, which is what we timed
