    Titration Lab of NaOH and KHP Aim: To titrate Sodium Hydroxide with Potassium Hydrogen Phthalate . To also determine the concentration of NaOH in the KHP solution. Hypothesis: When KHP is added to the solution of NaOH and the indicator‚ the solution will turn clear and neutralize. The concentration of NaOH is going to be very low because it is diluted. Materials required: pipette filler‚ volumetric flasks(2-4)‚ beakers(2)‚small white piece of paper‚ indicator( 2 drops)‚ conical flask‚ clamp

    Determination of KHP – Acid - Base Titration For determining purity of unknown KHP‚ acid – base titration was used. Molarity of titrant in this case NaOH was standardized as 0.04958(±0.00011) M. Purity of unknown KHP was calculated as 35.88(±0.16) %. • Introduction Acid – base titration is typical method of determining unknown figures. Acid – base titration means that by using neutralization between acid and base. Abrupt changing of pH says whether procedure is done or not. pH indicators

    Chemistry SL! Research Question! How is the solubility of sodium hydroxide (NaOH) in water affected by temperature? ! ! Introduction ! Sodium hydroxide is categorised as metal halide salt‚ composed of sodium and chlorine.! The ions present in the solid crystals of potassium chloride dissolve and gain mobility in water. When potassium chloride is dissolved in water‚ the following endothermic reaction occurs:! NaOH(s) + H2O(l) → Na+(aq) + OH–(aq) + H2O(l)! This reaction takes place because

    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

    an 0.1 M solution of NaOH. This was done by diluting from the 6 M solution that was provided. Next‚ 0.715g of KHP was weighed using the glazed paper and the triple beam balance. The KHP was then transferred to the 250 mL Erlenmeyer flask. Using a graduated cylinder‚ 50 mL of deionized water was measured and added to the flask. The KHP was dissolved in the water‚ and few drops of phenolphthalein were added. Moreover‚ the burette was rinsed with deionized water‚ then with NaOH solution. Then‚ it was
