een png foto van erlenmeyer but buret dus opstelling zuur-base titratie

A PNG image of an Erlenmeyer flask and burette set up for an acid-base titration. The Erlenmeyer flask houses a purple solution indicative of the basic solution. The burette, securely clamped vertically above the flask, contains a clear acidic solution. Both the flask and burette have clearly marked measurement scales. The burette is all set to slowly add the acid into the base in the Erlenmeyer flask. There should be a white background to increase the visibility
