Abstract
An experiment entitled “The Corellation Between CO₂, Temperature, and Salinity” was conducted to determine the interrelationship among carbon dioxide concentration (CO₂), temperature, and salinity in seawater. The instruments used in this experiment included an Erlenmeyer flask, volumetric flask, drop pipette, funnel, and sample bottle. The materials used were seawater, phenolphthalein indicator (PP), sodium hydroxide (NaOH), and sodium carbonate (Na₂CO₃). The method applied in this experiment was titration using NaOH solution. The results showed that the seawater sample tested positive for the presence of CO₂, as indicated by no color change after the addition of the phenolphthalein indicator. The removal of CO₂ from the sample was observed when the solution turned pink after titration with NaOH, confirming the success of the experiment.
