Hcl And Naoh
Title: The Effect of the Number of Drops of HCl and NaOH on the Net Change in the pH of Plant, Animal, and Nonbiological Solutions
Research Question: How do plants and animals respond to changes in pH?
Analysis Questions:
Summarize the effects of HCl and NaOH on the tap water.
HCl is an acid and when in tap water, dissociates into H+ and Cl-. Since it releases the H+ ion in the tap water, it raises the concentration of H+, which lowers the pH of the tap water. Unlike HCl, NaOH is a base. NaOH is a base because when in the tap water it separates into Na+ and OH-. Since it releases a OH- ion it lowers the concentration of H+ because the OH- combines with H+ to form water (H20) and therefore raises the pH of the tap water.
