How to Make EDTA Solution - Science Notes and Projects

WebIn experiments I had to reach pH of about 12 to strip the compound of the alcohol-proton, yielding a negative charge which interacts more strongly with water. Nonetheless you can still make a decently concentrated (~0.1M) solution of EDTA in water by stirring alone, if you allow a stir-plate to do the work for ~30 minutes. WebAfter some time you will see that the EDTA will start to dissolve in the solution. This happens as the result of the solution’s pH approaches 8 (base). Moreover, when the EDTA completely dissolves add one more gram of NaOH to the solution and stop stirring. Now add enough water for the solution to reach the 1-litre mark.
