An acid/base neutralization reaction will yield salt and water. Precipitation in solution 2. Titration (also known as titrimetry and volumetric analysis) is a common laboratory method of quantitative chemical analysis to determine the concentration of an identified analyte (a substance to be analyzed). Due to the leveling effect, the shape of the curve for a titration involving a strong acid and a strong base depends on only the concentrations of the acid and base, not their identities. Less than 0.2 to 0.3 mL of base should be used to see the first faint pink color. If you continue browsing the site, you agree to the use of cookies on this website.
