Webshifts in the water’s pH can affect the solubility of some metals such as iron and copper. Such changes can influence aquatic life indirectly; if the pH levels are lowered, toxic metals in the estuary’s sediment can be resuspended in the water column. This can have impacts on many aquatic species. See Chapter 12 for more infor WebAlkalinity can increase the pH (make water more basic), when the alkalinity comes from a mineral source such as calcium carbonate (CaCO 3). ... These points can be determined by measuring pH as the acid is added, or by choosing indicators that change color at the pH value of the equivalence point. The Alkalinity Test.
