Alkalinity Of Water Experiment Presentation

Introduction
The alkalinity of water refers to its ability to neutralize acids. Measuring alkalinity helps determine the water's buffering capacity. This experiment aims to investigate the alkalinity of different water samples.	Image Source

Materials and Methods
Collect water samples from different sources, such as tap water, well water, and river water. Measure 100 ml of each water sample using a graduated cylinder. Add a few drops of phenolphthalein indicator to each water sample.	Image Source
