What else can I help you with?
The pH scale is used to measure the amount of what atom?
The pH scale measures the amount of available H+ ions. Specifically pH=-log10[H+]
How does the concentration of H affect the number on the pH scale?
The meaning of a higher H+ concentration is a low pH.
What does the H stand for in the pH factor?
Hydrogen
How does the POH scale form PH scale?
pH + pOH = 14 pH is a measure of the hydrogen ion concentration, [H+] pOH is a measure of the hydroxide ion concentration, [OH-] pH = -log10[H+] pOH = -log10[OH-]
How are pH and logarithm related?
pH is a logarithmic scale used to specify the acidity or basicity of a solution. The pH scale ranges from 0 to 14, with lower values indicating acidity and higher values indicating basicity. pH = -log[H+], where [H+] is the concentration of hydrogen ions in the solution.
how does the pH scale is a mathematical indicator of?
The pH is a measure of the activity of the ion H+ (the negative logarithm in base 10); the scale is logarithmic.
How does an increase in the cocentration of H plus affect the number on the pH scale?
As the concentration of H+ increases, the value of pH decreases simultaneously.
Why is the pH scale significant?
The pH scale shows the relative acidity (H+ ions) and basicity (OH- ions) of a sample. A pH of <7.0 is acidic; a 7.0 pH is neutral and, one with a pH >7.0 is basic.
Is a scale that measures the acidity or basicity of a solution along a range of zero to 14.?
pH
What does the H stand for in pH the chemical measure of acidity?
hydrogen
What makes up PH scale?
The Ph scale doesn't have units it's a model to show where solutions rank based on the -Log of the concentration of H+ ions
What is p in pH?
pH is the scientific abbreviation for power of Hydrogen.p=power H=hydrogen. The "p" in pH comes from the notation of the probability of finding a Mole of H+ ions in a given amount of solution which is written as P(H+)=Moles of H+ per litre. Unfortunately the Probability expressed in numbers is not the ideal way to describe and compare things. The best way to do this is to have a scale and have everything fit between its extreemes. Thus the pH scale was devised where the negative log of the concentration of H+ ions gives a scale from 0 to 14. This does not mean that the definition of "p" in "pH" changed but it only says that the old name (probability of H+) is now being used to refer to the the "pH scale".
