This is a chemistry lab report on an Acid-Base Titration

The KIP solution will be poured in a flask along with a ewe drops of one of three indicators we will be evaluating. The Noah solution will be poured into a burette (with volume markers) and will be used as the iterant. The strong base will be added slowly to the acidic solution, gradually neutralizing…

Lab Report on milk co-motion.

When detergent is added to milk and the food color, the non-polar ends of the soap molecules attracts towards the non-polar fat of milk, and the interaction of the detergent with the fat in milk exults the food color to swirl around.
