Clitoria ternatea, or butterfly pea, is an easily accessible Asian flower that can function as a pH indicator. A method of preparing the butterfly pea flower indicator is described, then a pH color scale between pH 2 and 12 is shown. The indicator is stored over 8 days and tested to determine its reliability over time. It is concluded that the indicator solution has an effective shelf life of less than 5 days. A method for creating pH paper is then described and its pH color scale is shown. The…
