The pH scale is a measurement of the acidity or basicity of a substance in a solution. It is a logarithmic scale based on the concentration of hydrogen ions in solution. Hence, pH stands for "power of hydrogen". Answer and Explanation: ...
The pH scale is commonly used to represent hydrogen ion activity. On the pH scale, pH values below 7 represent acidic solutions (hydrogen ion activity greater than hydroxide ion activity) while values above 7 represent basic solutions. At pH = 7, hydrogen ion and hydroxide ion activity are eq...
The pH scale is, as previously mentioned, an inverse logarithm and ranges from 0 to 14 (Figure 1). Anything below 7.0 (ranging from 0.0 to 6.9) is acidic, and anything above 7.0 (from 7.1 to 14.0) is alkaline. Extremes in pH in either direction from 7.0 are usually considered ...
The following is the pH equation used to find the power of the hydrogen concentration ion and calculate pH of a solution: pH= -logH3O^+ This formula is needed when finding pH by using the given information of hydronium ion concentration. How do you calculate pH given molarity? When stud...
