Acids & Bases Lab Report
Lab report will be due by Monday, May 5th. You need to turn in only one lab report per team (teams of two people). If you joined a team of two people for whatever reason (total of three members), that person will have to submit a report individually with the team’s data and results. This report will count as an exam grade! Next slides will cover the requirements of the report

Acids & Bases Lab Report
You will re-write your data (data table for litmus and pH papers) and observations you saw during the second part of this lab (using indicators). Create a pH scale that will include the ten solutions you tested and their pH’s you approximated during the two labs. Your report MUST include the following: Data table, observations, a list of the solutions (given by me), and a complete discussion as to why the pH’s you approximated may not be what the actual pH’s of the solutions are. Please make sure you also discuss how your results could be improved!! Presentation goes A LONG WAY!!!
