The pH scaleis logarithmic, essentially meaning the difference in 1 pH unit is a difference of 10 times! What does P in pH mean? pH is the negative log of hydrogen ion concentration in a water-based solution. ... pH is an abbreviation for "power of hydrogen" where "p" is short for...
New stomach cells are constantly produced to replace dead ones, which are digested by the stomach acids. It is estimated that the lining of the human stomach is completely replaced every seven to ten days.Watch this video for a straightforward explanation of pH and its logarithmic scale.Buffers...
Why is the pH Scale Logarithmic? 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...
What is neutral on the pH scale? Potential of Hydrogen 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". ...
as the value increases. One interesting thing to note here is that the pH scale is not a linear scale. In other words, an acid with a ph of 3 is not twice as strong as an acid with a pH of 6. An important distinction to understand is that the pH scale is a logarithmic scale. ...
Above VEI 1, the scale becomes logarithmic, meaning that each step in the scale represents a 10X increase in the amount of material ejected. VEI 2 eruptions produce between 0.001 and 0.01 cubic kilometers of ejecta. VEI 3 eruptions produce between 0.01 and 0.1 cubic kilometers of ejecta. ...

The pH scaleis a logarithmic scale that usually runs from 1 to 14. Each whole pH value below 7 (thepH of pure water) is ten times more acidic than the higher value and each whole pH value above 7 is ten times less acidic than the one below it. For example, a pH of 3 is ten ...
