Chemistry write introduction Experiment Acid-Base Titration Using a pH Meter and Phenolphthalein Strong acid vs Strong base should state the purpose of the investigation and must include appropriate citations of relevant, precedent work but should not include an extensive review of marginally related literature. If the manuscript describes a new method, indicate why it is preferable to older methods. If the manuscript describes an improved analysis of a substance, the competing methods must be referenced and compared. use Hydrochloric acid
