実験手順

Example 4 illustrates that the addition of potassium hydroxide to sodium tripolyphosphate (wherein the level of the tripolyphosphate anion concentration was about equal to that which results by hydrolyzing 13.3% sodium trimetaphosphate with KOH) did not solubilize the sodium tripolyphosphate and a very heavy precipitate was observed.
