Which best describes the products of the reaction?<br>A. A clear gas.<br>B. A white solid<br>C. A clear liquid and clear gas<br>D. A clear liquid<\/p>\n\n\n\n<p><strong><mark style=\"background-color:rgba(0, 0, 0, 0)\" class=\"has-inline-color has-ast-global-color-6-color\">The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n<p>The correct answer is <strong>C. A clear liquid and clear gas<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Explanation:<\/h3>\n\n\n\n<p>When an antacid tablet dissolves in water, it typically reacts with the water to produce a chemical reaction. Antacid tablets often contain compounds like sodium bicarbonate (NaHCO\u2083), calcium carbonate (CaCO\u2083), or magnesium hydroxide (Mg(OH)\u2082), which react with acids such as hydrochloric acid (HCl) found in the stomach or sometimes in the water, to neutralize the acid and relieve indigestion.<\/p>\n\n\n\n<p>Here\u2019s a breakdown of the reaction:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Reaction of Sodium Bicarbonate with Water:<\/strong><br>A common example is the reaction of sodium bicarbonate with water:<br>[<br>NaHCO\u2083 (aq) \\rightarrow Na\u207a (aq) + HCO\u2083\u207b (aq)<br>]<br>The bicarbonate ion (HCO\u2083\u207b) reacts with the water (H\u2082O) to form carbonic acid (H\u2082CO\u2083), which is unstable and decomposes to produce carbon dioxide gas (CO\u2082) and water:<br>[<br>H\u2082CO\u2083 \\rightarrow CO\u2082 (g) + H\u2082O (l)<br>]<br>In this case, <strong>carbon dioxide gas (CO\u2082)<\/strong> is released as bubbles, and water remains as the liquid product.<\/li>\n\n\n\n<li><strong>Other Antacid Reactions:<\/strong><br>Similar reactions occur with other antacid components. For example, calcium carbonate (CaCO\u2083) reacts with water to form calcium ions (Ca\u00b2\u207a), bicarbonate ions (HCO\u2083\u207b), and carbon dioxide gas (CO\u2082). The carbon dioxide gas is responsible for the bubbling effect. This results in the formation of:<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A <strong>clear liquid<\/strong>, which is simply the water or aqueous solution that remains after the reaction.<\/li>\n\n\n\n<li>A <strong>clear gas<\/strong>, which is carbon dioxide (CO\u2082), a colorless and odorless gas.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Why Not the Other Options?<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A. A clear gas<\/strong>: While carbon dioxide gas is formed, there is also a liquid product (water), so the reaction produces both a gas and a liquid, not just gas.<\/li>\n\n\n\n<li><strong>B. A white solid<\/strong>: The reaction does not typically produce a solid (except under specific conditions), and antacids are usually designed to dissolve in water.<\/li>\n\n\n\n<li><strong>D. A clear liquid<\/strong>: Although the liquid is clear, this answer ignores the formation of carbon dioxide gas, which is a key product of the reaction.<\/li>\n<\/ul>\n\n\n\n<p>Thus, <strong>C<\/strong> is the best description, as it accurately reflects both the liquid and gas products of the reaction.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>An antacid tablet reacts in water, creating bubbles.
