It is important to keep mind that water (distilled, deionized, or tap) is NOT “pure” (i.e., pH equal to 7). The moment it comes in contact with air, CO 2 gas begins dissolving into it, forming carbonic acid. The actual pH, therefore, will typically be slightly less than 7. list of walt disney films
