Bacterial Morphology MLT1 Task 11- Lab 2 Johnny Archuleta Western Governors University Question A and C answers. A wet mount stain is when a drop of water is placed onto the microscope slide. The water on the slide helps to support the organism and sample. The water fills the space between the cover slip and the slide. This action allows the light from the microscope to pass through the slide and the sample for better visualization of the organisms. A direct stain occurs when a charged

different halide salts found in the body if various compounds are added to the halide? How will the halides react? Introduction: For this lab we tested 6 halide salts found in the body‚ and their reactivity when a compound is added. We tested the halides NaF‚ NaCl‚ KBr‚ KI‚ and two unknown halides. To find the reaction of the halide‚ we are adding drops of Ca(NO3)2‚ AgNO3‚ AgNO3 + Na2S2O3‚ and NaOCI + Starch to the halides. Each halide will be separated from each other and the drops of each compound
