WebAt 25 °C (77 °F ), solutions with a pH less than 7 are acidic, and solutions with a pH greater than 7 are basic. Solutions with a pH of 7 at 25 °C are neutral (i.e. have the same concentration of H + ions as OH − ions, i.e. the same as pure water ). WebJan 30, 2024 · If pH < 7, the solution is acidic. There are more H + than OH - in an acidic solution. The pH scale does not have an upper nor lower bound. Example 1 If the concentration of N a O H in a solution is 2.5 × 10 − 4 M, what is the concentration of H 3 O +? Solution We can assume room temperature, so 1.0 × 10 − 14 = [ H 3 O +] [ O H −] WebAcidic solutions have pH values less than 7, and basic solutions have pH values greater than 7.

WebThe pH scale measures how acidic an object is. Objects that are not very acidic are called basic. The scale has values ranging from zero (the most acidic) to 14 (the most basic). As you can see from the pH scale above, pure water has a pH value of 7. This value is considered neutral—neither acidic or basic. WebFeb 1, 2024 · A pH of 1 to 7 indicates an acidic solution. A pH of 7 to 14 indicates a basic solution. pH is important to know the health of the soil, pH values of waterbodies, rain and aquatic life health. Plants depend on soil pH for nutrients. Aquatic life's survival depends on the correct pH of oceans.

WebNov 29, 2024 · The pH scale ranges from 0 to 14, with 0 indicating extremely acidic and 14 indicating extremely alkaline. If a pH value of 7 is found in any solution, it indicates that the solution is neutral in nature. Values less than 7 suggest an acidic solution, whereas values more than 7 indicate an alkaline solution. WebMay 6, 2024 · pH describes how acidic or basic an aqueous solution is, where a pH below 7 is acidic and a pH greater than 7 is basic. pH of 7 is considered neutral (e.g., pure water). Typically, values of pH range from 0 to 14, although very strong acids may have a negative pH, while very strong bases may have a pH exceeding 14.

WebExample. Thus, the pH of an acidic solution of HNO 3 (10 –3 M) = 3, a basic solution of KOH having [OH –] =10 –4 M and [H 3 O +] =10 –10 M will have a pH = 10. pH of acids is generally less than 7 whereas for bases it is greater than 7. At 298 K, ionic product of water, K w can be given as:. K w = [H 3 O +] [OH –] = 10 –14. Taking the negative logarithm of RHS and …

WebMar 3, 2024 · If pH < 7, then the solution is acidic. If pH = 7, then the solution is neutral. If pH > 7, then the solution is basic. This is known as the pH scale and is the range of values from 0 to 14 that describes the acidity or basicity of a solution.
