In the experiment, excess HCl was added to ensure that all KHCO3 was reacted. Excess reactants ensure that all of the limiting reactant is completely consumed in the reaction, leaving none unreacted. When all KHCO3 reacts, the reaction reaches completion.
How about a ton of drawings and illustrations? Use the link below and there will be more than you can do. By the way, the experiment is usually called the Geiger-Marsden Experiment as it was done by these two researchers. There is a link to the Wikipedia post on this experiment below as well.
Yu can play around
A good chemistry experiment for experts is how magnetism affects plant life. Some very good research can be done on this subject.
It is the salt solution and distilled water
because it helps you understand if you have done the experiment correctly or not to see if you have the same answers as the other people
In the experiment, excess HCl was added to the solution containing KHCO3. This ensured that all of the KHCO3 would react completely, as any unreacted KHCO3 would still be neutralized by the excess HCl.
The reason for the experiment is to answer the problem
Experiment done the most is doing hypothesis
The necessary safety precautions when conducting an experiment depend on what is done during the experiment and where it is done.
a controlled experiment is an experiment that has an iv, dv, and a control, is in a well handled environment, and the experiment is safely done.
It is the "aim"
No
The data should be organized and the experiment's materials cleaned?
The scientific method that should be done throughout an experiment is to state the problem.
It depends on what your experiment was. You should ask a teacher or someone that you know who has done this before.
It shows that the experiment is designed properly.
