What Are the Effects of Sulfuric Acid on Metal? - wiseGEEK

6/8/2020· Some metal sulfates — for example, those of iron, zinc and aluminum — are very soluble in water or acids while others — like the sulfates of calcium and barium — are not. When the sulfate has low solubility, the reaction will quickly slow down or stop as …

Potassium - Periodic Table

In the periodic table, potassium is one of the alkali metals. All of the alkali metals have a single valence electron in the outer electron shell, which is easily removed to create an ion with a positive charge – a ion, which coines with anions to form salts.
