This means that sulfur dioxide has the ability to form four bonds or combine with four other atoms or groups of atoms.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-contrast=\"none\">7: Is SO<\/span><span data-contrast=\"none\">2<\/span><span data-contrast=\"none\"> acidic or basic gas?<\/span><span data-ccp-props=\"{&quot;201341983&quot;:1,&quot;335559739&quot;:160,&quot;335559740&quot;:360}\"> <\/span><\/p>\n<p><span data-contrast=\"auto\">Answer: SO<\/span><span data-contrast=\"auto\">2<\/span><span data-contrast=\"auto\"> is an acidic gas. When sulfur dioxide dissolves in water, it forms sulfurous acid (H<\/span><span data-contrast=\"auto\">2<\/span><span data-contrast=\"auto\">SO<\/span><span data-contrast=\"auto\">3<\/span><span data-contrast=\"auto\">), which is a weak acid. Sulfurous acid can release hydrogen ions (H+) in solution, leading to an acidic pH.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-ccp-props=\"{&quot;201341983&quot;:1,&quot;335559739&quot;:160,&quot;335559740&quot;:360}\"> <\/span><\/p>\n<p><span data-contrast=\"none\">8: Does SO<\/span><span data-contrast=\"none\">2<\/span><span data-contrast=\"none\"> cause acid rain?<\/span><span data-contrast=\"auto\"> <\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-contrast=\"auto\">Answer:<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n<p><span data-contrast=\"auto\">Yes, SO<\/span><span data-contrast=\"auto\">2<\/span><span data-contrast=\"auto\"> is one of the main contributors to acid rain. When sulfur dioxide is released into the atmosphere through industrial processes or burning of fossil fuels, it can react with oxygen, moisture, and other atmospheric components to form sulfuric acid (H<\/span><span data-contrast=\"auto\">2<\/span><span data-contrast=\"auto\">SO<\/span><span data-contrast=\"auto\">4<\/span><span data-contrast=\"auto\">). Sulfuric acid is a strong acid that can contribute to the acidity of rainwater, resulting in acid rain. Acid rain can have detrimental effects on ecosystems, forests, bodies of water, and human-made structures.<\/span><span data-ccp-props=\"{&quot;201341983&quot;:0,&quot;335559739&quot;:160,&quot;335559740&quot;:259}\"> <\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sulfur dioxide (SO2) is a colorless gas with a pungent odor.
