What is the correct chemical formula for strontium hydroxide? Select one: Sr(OH)2<\/p>\n\n\n\n

The correct answer and explanation is:<\/strong><\/mark><\/p>\n\n\n\n

The correct chemical formula for strontium hydroxide is Sr(OH)\u2082<\/strong>.<\/p>\n\n\n\n

Explanation:<\/h3>\n\n\n\n

Strontium hydroxide is an ionic compound made up of strontium ions and hydroxide ions. To understand why the formula is Sr(OH)\u2082, let’s break down the components:<\/p>\n\n\n\n

    \n
  1. Strontium (Sr)<\/strong> is an alkaline earth metal found in Group 2 of the periodic table. Elements in this group typically form ions with a +2 charge because they lose two electrons to achieve a stable electron configuration. Therefore, the strontium ion is Sr\u00b2\u207a<\/strong>.<\/li>\n\n\n\n
  2. Hydroxide (OH\u207b)<\/strong> is a polyatomic ion consisting of one oxygen and one hydrogen atom, carrying a -1 charge.<\/li>\n<\/ol>\n\n\n\n

    To form a neutral compound, the total positive charge must balance the total negative charge. Since strontium has a +2 charge (Sr\u00b2\u207a) and hydroxide has a -1 charge (OH\u207b), two hydroxide ions are needed to balance one strontium ion:<\/p>\n\n\n\n

      \n
    • 1 \u00d7 Sr\u00b2\u207a = +2 charge<\/li>\n\n\n\n
    • 2 \u00d7 OH\u207b = 2 \u00d7 (-1) = -2 charge<\/li>\n<\/ul>\n\n\n\n

      Adding these charges together:<\/p>\n\n\n\n

      +2 + (-2) = 0 (neutral compound)<\/p>\n\n\n\n

      Hence, the formula is Sr(OH)\u2082<\/strong>, indicating one strontium ion combined with two hydroxide ions.<\/p>\n\n\n\n

      Additional notes:<\/h3>\n\n\n\n
        \n
      • The parentheses around (OH) indicate that the hydroxide ion acts as a single polyatomic group. The subscript \u2082 applies to the entire hydroxide ion, not just to hydrogen or oxygen separately.<\/li>\n\n\n\n
      • Strontium hydroxide is commonly used in chemical synthesis and industrial applications, such as in water treatment and as a precursor to other strontium compounds.<\/li>\n\n\n\n
      • The compound is typically found as a hydrate in nature, often as Sr(OH)\u2082\u00b78H\u2082O, but the basic formula remains Sr(OH)\u2082.<\/li>\n<\/ul>\n\n\n\n

        In summary, the correct chemical formula for strontium hydroxide is Sr(OH)\u2082<\/strong>, reflecting the ionic charges and the need for charge neutrality in the compound.<\/p>\n","protected":false},"excerpt":{"rendered":"
