Preparing a Titration Standard in 250 ml
Weigh the primary standard, tip it into the flask through a funnel and wash every trace in with distilled water. Swirl until it has fully dissolved before filling to the neck, then bring the bottom of the meniscus up to the mark with a dropper. Turn the stoppered flask upside down repeatedly until the solution is uniform. Hot solutions must cool first, because warm liquid takes up more volume than the mark allows for.
A 250 ml batch fills a burette and still leaves enough for several pipetted portions, so every titration in the practical starts from the same known concentration.
