A base that is dissolved in water produces hydroxide ions, which are also known as hydroxyl ions. A hydroxide ion has one oxygen atom and one hydrogen atom. More »

When metal oxides are put into contact with water, they often, though not always, form metal hydroxides. The reaction depends on the element, the acidity of the metal oxide and on the physical state of the water. More »

In the cells of eukaryotic organisms, the subunits that will become ribosomes are produced within the subnuclear structure called the nucleolus, and the subunits then combine in the cell's cytoplasm to become functioning... More »

Chemically, the difference between the two is that hard water contains calcium and magnesium ions, while soft water does not. Soft water is easier to lather with than hard water is. More »

All metallic oxides that react with water to form a base solution are considered basic anhydrides, including lithium, magnesium, sodium and calcium oxides. Only the oxides formed by the alkali metals and alkali earth met... More »

The chemical formula (NH4)20 represents 20 ions of the compound for the ammonium cation. NH4 is the chemical formula for ammonium, and the 20 after the parenthesis indicates that there are 20 ammonium ions. More »
