Acid Base Titration

An acid-base titration is the method of quantitative analysis for determining the concentration of an acid and base by exactly neutralizing it with a standard solution of base or acid having known concentration.

Question

Salinity of seawater is S% = 3.35%, density if seawater is d = 1.025 g/mL.
