investigating the properties of unknown acids and bases

 

In this lab we add indicators to the solution to find out if the unknown substance was acidic, basic or neutral. What we did first was label the spot plate for the solutions and the indicators. then we added 7 drops of each unknown solution in the spot plate and we added a drop of an indicator into each spot on the plate and observed what the colour was and if it was a base or acid. The first picture is before we added ten indicators and the other picture is after we added the indicators. I believe on all the core competencies I should receive a 4 on each section because as I was doing the lab I gain knowledge of acids and bases I worked great with my partner and did all of the directions property. made good observations before and after the lab.
