Titration Practical Abstract The aim of this practical is to see how much Dilute Sulphuric Acid needs to be added to the Sodium Hydroxide to neutralise it. This is done by using a pink colour indicator (Phenolphthalein Indicator Solution) once the solution has turned clear this means that it has then been neutralised. I found that the solutions were made quite well as the reactions were completed quickly and within the range that was predicted. When performing the experiment I found that the equipment was very accurate making the measurements correct and increasing the reliability of the experiment. I predict that the lab technician’s Sodium Hydroxide will be a better solution than the one I made myself. So my prediction is that it will take more Sulphuric Acid to neutralise the solution when I use the Sodium Hydroxide that I made myself. Equipment List • Sodium Hydroxide Pellets • Phenolphthalein Indicator Solution • Dilute Sulphuric Acid • Distilled Water • Weighing Boat • Scales • Volumetric Flask • Conical Flask • Funnel • 25ml Pipette • Burette • White Tile • Spatula • Goggles • Gloves Method for Standard Solution Measure out 10 grams of Sodium Hydroxide pellets in a weighing boat using the scales. Place the pellets into the volumetric flask and add distilled water to make the solution 250ml. Swirl the flask to ensure that all the pellets have dissolved. Shake the solution well until it has turned clear. Method Ensure that the burette is clamped into the burette stand and the tap on the burette is closed. Use a funnel to fill the burette with Sulphuric Acid, make sure that the meniscus is level with the zero mark. Use a funnel to fill the measuring cylinder to 25ml with Sodium Hydroxide Solution. Add the 25ml of Sodium Hydroxide Solution into the conical flask and then add three drops of Phenolphthalein Indicator Solution. Use a
