After the enzyme reaction begun we measured the height of the froth in test tubes A to D.
The table was prepared and the results had been jotted down. We also repeated the experiment for reliable results. Results: pH Foam Measured 1st Attempt Foam Measured 2nd Attempt Average mm mm m 41. Mm mm m mm m mm m mm m 1 mm mm mm m 86. Mm Conclusion: The results above show that pH 7 had the highest average foam height.The enzyme is working its best as pH is the optimum pH for the enzyme. Evaluation: Overall the experiment worked well however there might have been a tee minor errors for example the amount of detergent dropped into the test tubes could have changed the results and also the pH labels might have been labeled wrong.
Another error could have been poor timing, the test tubes being in the water bath for too long could have altered the results.
