Which formula represents lead(II) hydroxide? Pb(OH)2<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n The correct formula for lead(II) hydroxide is Pb(OH)\u2082<\/strong>.<\/p>\n\n\n\n Explanation:<\/p>\n\n\n\n Lead(II) hydroxide is an inorganic compound composed of lead, oxygen, and hydrogen atoms. To understand why its formula is Pb(OH)\u2082, consider the charges of the ions involved.<\/p>\n\n\n\n Lead in this compound is in the +2 oxidation state, indicated by the Roman numeral II in lead(II). This means the lead ion is Pb\u00b2\u207a. The hydroxide ion is OH\u207b, a polyatomic ion with a charge of -1.<\/p>\n\n\n\n Since the compound must be electrically neutral, the total positive charge must balance the total negative charge. One Pb\u00b2\u207a ion requires two OH\u207b ions to balance the charge: Therefore, the chemical formula combines one lead ion with two hydroxide ions, producing Pb(OH)\u2082.<\/p>\n\n\n\n This type of compound is classified as a hydroxide and is generally considered a base in chemistry. Lead(II) hydroxide is a solid under standard conditions and has limited solubility in water, often forming a precipitate when lead salts react with hydroxide ions in solution.<\/p>\n\n\n\n Understanding the formula also involves knowledge of ionic bonding. The Pb\u00b2\u207a and OH\u207b ions attract each other electrostatically, forming an ionic compound. The parentheses around the OH indicate that the hydroxide group remains intact as a unit, and the subscript 2 applies to the whole hydroxide ion, meaning there are two hydroxide groups for every one lead ion.<\/p>\n\n\n\n In summary, Pb(OH)\u2082 correctly represents lead(II) hydroxide because the lead ion’s +2 charge is balanced by two hydroxide ions, each with a -1 charge. This chemical formula is consistent with the rules of ionic compound formation and charge neutrality.<\/p>\n","protected":false},"excerpt":{"rendered":" Which formula represents lead(II) hydroxide?
