Apparatus Burette Volumetric Pipette Beakers Conical Flasks Volumetric Flasks Funnel Clamp Stand White Tile Method Measure out 25cm3 of Methanoic acid of known concentration for the titration using the volumetric pipette. Assemble apparatus (as shown in diagram) after collecting goggles and lab coat for safety. Move your apparatus to eve level (i.e. to a stool) and pour the Methanoic acid in till the meniscus rests on the 0 level exactly so that your results can be measured accurately from the same marker every time. Move the apparatus back onto the table, and measure 25cm3 of methanoic acid accurately with the volumetric pipette (ensuring that it is clean, washed with distilled water then the solution you are using) and pour it into a conical flask. Add a few drops of phenolphthalein indicator which will make the solution pink and you can...
