Standardization Of Naoh

STANDARDIZATION OF SODIUM HYDROXIDE, NaOH (aq) Aim The aim was to determine the submerging of sodium Hydroxide. Safety In differentiate to observe any accidence during the titration process, or so safety precautions were observed. Goggle was employ throughout the experiment to prevent the corrosive action of atomic number 11 Hydroxide origin from make the eyes. Gloves were tightly worn on the two hands to suspend the corrosive action of the base. The conic flask containing the KHP chair was live on firmly to the dishearten splay air to avoid it from falling rancid the board in the process of sucking the base. The table surface was pick of all the spills to avoid skin contact. Again, all chemic utilize were disposed of properly after the titration. Equipments * 50cm3 buret, * 25cm3 pipette, * 250cm3 beaker, * Ring wheel with clamp, * Funnel, * 250ml Erlenmeyer (conical) flask, * colour roofing tile, * Sodium Hydroxide re etymon, * Potassium Hydrogen Phthalate and * Phenolphthalein. Methods The burette was initiatory rinse with the solution of NaOH (aq) and so fill with homogeneous solution measuring up to the zero mark. The initial burette extension was read and record made in the examination towboat.

Again, the pipette was rinse with KHP, filled up to the 25 cm3 use the pipette filler, and thence care honorabley transferred to the 250cm3 conical flask. Added to the KHP solution was the phenolphthalein solution and then was mix together. Here, there was no colour change. The sporting tile was abode on the ring stand. Then the beaker containing the Na OH solution was place on the tile for optimu! m visibility. The tap was open to place the NaOH solution into the flask. The flask was kept swirling as the NaOH solution drops into the beaker presently above it until the solution turns pink. The final burette yarn was then determined and record in the trial column of the result table. The burette was again top with NaOH solution and the initial reading recorded to...If you want to get a full essay, order it on our website: OrderEssay.net
