Error sources for gas measurement

Post by faisal » Wed Nov 23, 2005 7:47 pm

Can you think of any sources of error when meassuring the rate of a reaction for an enzyme controlled reaction, 1 could be the sources of experimental error in the experiment, when meassuring the ammount of gas released from a conical flask into a gas syringe?
I already have a few and equire a few more?

What have you got? That would probably make it easier for us.

an enzyme is placed in a conical flask when hydrogen peroxide is added to the enzyme oxygen gas is released, i am using a meassuring cylinder to meassure the volume of gas released, i am investigating how the pH effects the rate at which catalase is broken down, for 2 of my results from pH6-7 there were extreemly high error bars which suggests that lots of error were made when carrying out the investigation, i'v identified a few possible errors, but i need a few more

Did you have more gas or less gas? Maybe the bottle is broken or something..
By the way, catalase is not broken down, it breaks down H2O2 into H2O and O2

errors in measuring rate

Maybe the quality of the materials used, like the purity of the substances.

How about taking measurements at rtp
