Science Buddies: "Ask an Expert"

i am having trouble writing the lab report.
what will the IV, DV constants and control be for this project. https://www.sciencebuddies.org/science- ... /Chem_p087
when i did this project i forgot to take the ph of magnesium sulfate before passing the current so can anyone tell the ph of magnesium sulfate and also what causes the change in ph. Help me plzz my labreport is due soon.

https://www.sciencebuddies.org/science- ... p087.shtml for this experiment what causes the change in pH of salt solution

Hello treasure,

In this experiment you measure pH and how it changes with time. Think about that. What do you change independently and what do you measure that depends on it? As for a control, to what do you compare all your pH measurements?

The project description has a long "Introduction" section that discusses pH and why it changes in this experiment. Please consult that section again and submit any specific questions about any part you don't understand.

Good luck, WW

I did the experiment: Salt Bridge over Electrified waters, and I'm writing the lab report. I'm sort of lost on how to do the data analysis. I need ideas on what more to analyze. I already confirmed my hypotheses and talked about the data, but my teacher says it's not enough. What should I do?

Did you do all of the recording and graphing steps from the "Tracking the pH changes" section in the Procedure? If so, I'm not sure what your teacher wants. Perhaps you should ask your teacher.
