Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

Aquatic plants live in both the benthic and pelagic zones, and can be grouped according to their manner of growth: ⑴ emergent = rooted in the substrate, but with leaves and flowers extending into the air; ⑵ floating-leaved = rooted in the substrate, but with floating leaves; ⑶ submersed = growing beneath the surface; ⑷ free-floating ...
Sea Life Michigan Aquarium is the state's largest aquarium [citation needed] with over 250 species and 2,000 creatures including sharks, rays, and green sea turtles. Exhibits include freshwater lakes, coral reef, shipwreck, an interactive touch pool and a 180 degree underwater ocean tunnel.

Michigan's 20 largest inland lakes. This is a list of lakes in Michigan. The American state of Michigan borders four of the five Great Lakes. The number of inland lakes in Michigan depends on the minimum size. There are: 62,798 lakes ≥ 0.1 acres (0.00040 km 2) [1] 26,266 lakes ≥ 1.0 acre (0.0040 km 2) [1] 6,537 lakes ≥ 10.0 acres (0.040 ...
A universal indicator is a pH indicator made of a solution of several compounds that exhibit various smooth colour changes over a wide range pH values to indicate the acidity or alkalinity of solutions. A universal indicator can be in paper form or present in a form of a solution. [1]
In and of themselves, pH indicators are usually weak acids or weak bases. The general reaction scheme of acidic pH indicators in aqueous solutions can be formulated as: HInd (aq) + H 2 O (l) ⇌ H 3 O + (aq) + Ind − (aq) where, "HInd" is the acidic form and "Ind −" is the conjugate base of the indicator. Vice versa for basic pH indicators ...
The ponds or basins may range in depth from 1.5 to 5.0 meters. [ 6 ] In a surface-aerated system, the aerators provide two functions: they transfer air into the basins required by the biological oxidation reactions, and they provide the mixing required for dispersing the air and for contacting the reactants (that is, oxygen, wastewater and ...
