Pure water, at 25\u00b0C, has a neutral pH of 7. This means it has an equal concentration of hydrogen ions (H\u207a) and hydroxide ions (OH\u207b), each being 1 \u00d7 10\u207b\u2077 M. When the concentration of H\u207a ions in a solution increases above this value, the solution becomes <strong>acidic<\/strong>, and when it decreases, the solution becomes <strong>basic (alkaline)<\/strong>.<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Acidic Solutions<\/strong>:<br>An <strong>acidic<\/strong> solution has a higher concentration of hydrogen ions (H\u207a) compared to pure water. Acids are substances that release hydrogen ions when dissolved in water. The pH scale, which ranges from 0 to 14, measures the acidity or alkalinity of a solution. A pH value less than 7 indicates an acidic solution. As the concentration of H\u207a ions increases, the pH decreases. For example, hydrochloric acid (HCl) dissociates in water to release H\u207a ions, thus lowering the pH and making the solution acidic.<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Example: Lemon juice and stomach acid have a pH around 2\u20133, indicating high H\u207a concentrations.<\/li>\n<\/ul>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Basic (Alkaline) Solutions<\/strong>:<br>A <strong>basic<\/strong> or <strong>alkaline<\/strong> solution has a lower concentration of hydrogen ions than pure water, meaning it has a higher concentration of hydroxide ions (OH\u207b). Bases are substances that can accept hydrogen ions or donate hydroxide ions. A basic solution has a pH greater than 7. As the concentration of OH\u207b ions increases, the concentration of H\u207a ions decreases, making the solution less acidic.<\/li>\n<\/ol>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Example: Solutions like sodium hydroxide (NaOH) are basic. When NaOH dissolves in water, it dissociates into Na\u207a and OH\u207b ions, increasing the OH\u207b concentration and raising the pH.<\/li>\n<\/ul>\n\n\n\n<p>In summary, an <strong>acidic<\/strong> solution has a concentration of hydrogen ions greater than pure water, while a <strong>basic<\/strong> solution has a lower concentration of hydrogen ions. These variations in ion concentrations determine the pH and influence the chemical properties of the solution.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>An ________ solution has a concentration of hydrogen ions more than that of pure water.
