Problem 18.51

Magnesium ions are removed in water treatment by the addition of slaked lime, \(\mathrm{Ca}(\mathrm{OH})_{2}\). Write a balanced chemical equation to describe what occurs in this process.

Text Transcription:

Ca(OH)2

Step-by-Step Solution:

Step 1 of 5) The electrolytic process used commercially to produce aluminum is the Hall–Héroult process, named after its inventors, Charles M. Hall and Paul Héroult. Hall (1863–1914) (Figure 20.31) began working on the problem of reducing aluminum in about 1885 after he had learned from a professor of the difficulty of reducing ores of very active metals. Before the development of an electrolytic process, aluminum was obtained by a chemical reduction using sodium or potassium as the reducing agent, a costly procedure that made aluminum metal expensive. As late as 1852, the cost of aluminum was $545 per pound, far greater than the cost of gold. During the Paris Exposition in 1855, aluminum was exhibited as a rare metal, even though it is the third most abundant element in Earth’s crust.
