In a separating funnel, the <strong>denser<\/strong> liquid always settles at the <strong>bottom<\/strong>, while the <strong>less dense<\/strong> liquid floats on top.<\/p>\n\n\n\n<p>Here are the densities at 20\u00b0C:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Water<\/strong>: 1.00 g\/mL<\/li>\n\n\n\n<li><strong>Dichloromethane<\/strong>: 1.33 g\/mL<\/li>\n\n\n\n<li><strong>Diethyl ether<\/strong>: 0.71 g\/mL<\/li>\n<\/ul>\n\n\n\n<p>When a mixture of <strong>water and dichloromethane<\/strong> is placed in a separating funnel:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Dichloromethane is <strong>denser<\/strong> than water (1.33 g\/mL vs. 1.00 g\/mL).<\/li>\n\n\n\n<li>Therefore, <strong>dichloromethane<\/strong> will form the <strong>lower<\/strong> layer.<\/li>\n\n\n\n<li>Water, being less dense, will form the <strong>upper<\/strong> layer.<\/li>\n<\/ul>\n\n\n\n<p>On the other hand, if the mixture is <strong>water and diethyl ether<\/strong>:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Diethyl ether has a <strong>lower density<\/strong> than water (0.71 g\/mL vs. 1.00 g\/mL).<\/li>\n\n\n\n<li>This means <strong>diethyl ether<\/strong> will float on <strong>top<\/strong>.<\/li>\n\n\n\n<li>Water will form the <strong>bottom<\/strong> layer in this case.<\/li>\n<\/ul>\n\n\n\n<p>Since the question asks which one forms the <strong>lower layer<\/strong> in the separating funnel, we are looking for the solvent that is <strong>denser than water<\/strong>.<\/p>\n\n\n\n<p>Only <strong>dichloromethane<\/strong> has a density greater than water, so it will sink and form the lower layer.<\/p>\n\n\n\n<p><strong>Conclusion<\/strong>:<br>When considering the relative densities of water, dichloromethane, and diethyl ether, <strong>dichloromethane<\/strong> is the heaviest and will occupy the <strong>bottom<\/strong> layer in the funnel. This is a key property used in liquid-liquid extractions during organic chemistry experiments, allowing efficient separation of two immiscible layers.
