Most people are familiar with the words\u00a0acid<\/em> and\u00a0acidic<\/em>\u2014whether it’s because of acid rain or acidic foods like lemon juice. However, fewer people are aware of acid’s opposite: base\u00a0<\/em>(also called\u00a0alkaline<\/em>). Basic substances include things like baking soda, soap, and bleach. Distilled water is a neutral substance. The pH scale, which measures from 0 to 14, provides an indication of just how acidic or basic a substance is.<\/p>\n

Most parts of our body (excluding things like stomach acid) measure around 7.2 and 7.6 on the pH scale (a 7 is neutral on the scale). If foreign strong substances dramatically change this pH, our bodies can no longer function properly.<\/p>\n

In this outcome, we’ll learn about acids and bases, and what impact they can have on living systems.<\/p>\n\n\t\t\t
