Color changes 2. Precipitate (formation of a solid) 3. Formation of gas bubbles Procedure: (1 of 20 points) No preliminary dilution of my test chemicals were necessary as Lab Paq provided pre-diluted chemicals. Utilizing the 96-well plate‚ 2 pipet drops of each chemical were added to the wells in

Attach the stopcock to the tip of the titrator by placing the larger‚ clear‚ plastic end of the stopcock into the tip of the titrator and then twisting the stopcock into place. The stopcock should fit tightly into the titrator‚ so that the liquid will not leak. 4. Stack the textbooks on top of one another or stack two textbooks on top of the LabPaq box. 5. Clamp
