What is the colour of phenophthalein in tap water?
That depends on your tap water. Here where I live, the water is soft so its pH is quite low, 6.5 or 7, which means phenolphthalein is colourless. In some places it can be much higher, particularly where there is a lot of temporary hardness. Water companies work to the standard that pH should not exceed 9.5. Phenolphthalein changes colour over the range 8.2 to 10, so in very hard water it might show some pink.
