To prepare borscht reagent, you typically combine a concentrated solution of phenolphthalein with a potassium hydroxide (KOH) solution. First, dissolve around 1 gram of phenolphthalein in a small amount of ethanol, then slowly add this to 100 mL of a 1 M KOH solution while stirring. This reagent is often used for detecting the presence of alkaline substances in various chemical tests. Always remember to label the solution and store it appropriately.
