How does the concentration of hydrogen ions vary with pH?
pH is the negative log of the hydrogen ion concentration. So lowering pH from 5 to 4 means a ten times increase in hydrogen ion concentration. Increasing pH by 1 results in decreasing hydrogen ion concentration to 1/10th its former level.
What does element's atomic number represent?
The number of Protons in an atom, so Hydrogen with 1 proton has the atomic number 1.
Which change shows a 10 fold increase?
Many changes show a 10 fold increase, but if you are talking about every day chemistry phenomena, then it would be pH. Every change of 1 pH unit represents a 10 fold change in the hydronium ion concentration.
If pH decreases by 1 pH number on the scale then how much has the concentration of hydrogen ions increased by?
the hydrogen ion conc=0.1
What are the types of pH under which a substance may fall?
the typical scale for pH is between 0 and 14 however pH is defined as the -log10 (Concentration of H+ ions) so theoretically the range can exceed the values given in acidity or alkylinity. however bear in mind that pH is a logarithmic scale so an increase or decrease in pH by 1 means it is ten times more alkaline or acidic respectively
What does an increase 1 pH number represent?
A decrease in hydrogen ion concentration by factor of 10
What does an increase of 1 pH number represent?
10x increase in acidity
What does an increase pH of 1 represent?
A decrease in hydrogen ion concentration by factor of 10
What are ways to increase glucose transport?
1. increase the number of glucose carriers2. increase glucose concentration
If stomach acid has a PH of 1 and a person took a tums tablet which raised the PH to 3 how much was the increase in PH?
the increase in PH = 3 - 1 = 2
What does an increase of 1 number represent?
A decrease in hydrogen ion concentration by factor of 10
How is the pH scale similar to the Richter scale?
Both the pH scale and the Richter scale are logarithmic. A decrease of 1 on the pH scale means a tenfold increase in acidity while an increase of 1 on the Richter scale means a tenfold increase in intensity.
What is a numerical symbol used to represent the negative logarithm of the number of hydrogen ions present in 1 liter of a solution?
pH 0-14
Which change shows a tenfold increase in concentration h ions?
pH 2 -> pH 1
What numbers on the pH scale represent acids?
All numbers below 7. Acidity increases with decreasing number, for example, 1 is the most acidic.
Which changes shows a tenfold increase in concentration of H plus ions?
its pH 2 ---> pH 1
What does a change in pH of one unit represent in terms of hydrogen ion concentration?
-1 pH unit = *10 concentration
