The present study evaluated the role of natural indicators for estimating the alkalinity of water. The study was carried out volumetrically and the indicators used were the extracts of red cabbage , red radish and cherries. Carbonate and bicarbonate alkalinity of water was estimated by titrating an...

Alkalinity in water is a measure of ability of water to neutralize acids .Alkalinity in water causes nutritional imbalance to human health. Highly alkaline water may lead to caustic embrittlement . Bicarbonates of calcium and magnesium induce temporary hardness in water and hence it is essential to...
