What is the difference between pH and hydrogen ion concentration?

pH is a measure of the acidity or alkalinity of a solution on a logarithmic scale ranging from 0 to 14, while hydrogen ion concentration refers to the actual amount of H+ ions present in a solution. pH is calculated based on the negative logarithm of hydrogen ion concentration, where a lower pH value indicates higher hydrogen ion concentration and greater acidity.


What is the physical basis of pH?

pH is a measure of the concentration of hydrogen ions in a solution. It is based on the negative logarithm of the hydrogen ion concentration. A lower pH value indicates a higher concentration of hydrogen ions, making the solution more acidic, while a higher pH value indicates a lower concentration of hydrogen ions, making the solution more basic.


The strength of an acid based on concentration of what ions?

Hydrogen ion (H+) [technically it is hydronium ion (H3O+)] that determines the strength of an acid. A mole of hydrochloric acid (HCl) produces 1 mole of H+ ions, then that is a strong acid. Weak acids give smaller amounts of H+ for a mole of substance.


What is iodine on the pH scale?

Iodine itself is not measured on the pH scale, as pH specifically measures the acidity or alkalinity of a solution based on hydrogen ion concentration. Iodine is a chemical element and is often used as a reagent in various chemical reactions, but it does not have a pH value. When dissolved in water, iodine can form iodine species that may affect the pH of the solution, but iodine in its elemental form does not directly correspond to a pH level.


What pH satnds for in pH indicator?

pH stands for "potential of hydrogen." It is a measure of the acidity or alkalinity of a solution, ranging from 0 (most acidic) to 14 (most alkaline). pH indicators are substances that change color based on the pH of a solution, allowing for easy visual determination of its acidity or alkalinity.

How does a pH probe work to measure the acidity or alkalinity of a solution?

A pH probe works by measuring the concentration of hydrogen ions in a solution. The probe contains a special sensor that generates a small voltage based on the hydrogen ion concentration. This voltage is then converted into a pH value, which indicates the acidity or alkalinity of the solution.


The pH scale measures the concentrations of what ions in solutions?

It shows the concentration of H+ ions (if pH is less than 7) or OH- ions (if pH is above 7). pH + pOH = 14


What is the abbreviation for pH?

pH is the abbreviation for "potential for Hydrogen"


How does a pH sensor work to measure acidity or alkalinity in a solution?

A pH sensor measures the concentration of hydrogen ions in a solution to determine its acidity or alkalinity. The sensor contains a special electrode that generates a voltage signal based on the hydrogen ion concentration. This signal is then converted into a pH value, which indicates the level of acidity or alkalinity in the solution.


How does a pH sensor work to measure acidity or alkalinity levels in a solution?

A pH sensor measures the concentration of hydrogen ions in a solution to determine its acidity or alkalinity. The sensor contains a special electrode that generates a voltage signal based on the hydrogen ion concentration. This signal is then converted into a pH value, which indicates the acidity or alkalinity of the solution.


The strenghth of an acid is based on the concentration of what ions?

The strength of an acid is based on the concentration of hydrogen ions. Any compound with hydrogen in front of it, such as hydrochloric acid (HCl) is acidic.

A pH probe works by measuring the concentration of hydrogen ions in a solution. It contains a special sensor that generates a small voltage based on the hydrogen ion concentration, which is then converted into a pH value. This value indicates the acidity or alkalinity of the solution, with lower pH values indicating acidity and higher values indicating alkalinity.


What is a solution of known concentration used in the process of titration?

A standard solution is a solution of known concentration used in titration to determine the concentration of an unknown solution. It is usually added to the unknown solution until a desired reaction is completed, allowing the concentration of the unknown solution to be calculated based on the volume of standard solution used.


What is the pH scale based on?

pH scale ranges from 0 - 14. It measures the acidity or basicity of a solution. A measurement of 7 is neutral, less than 7 is acidic and a basic is higher than 7. pH is measured based on the concentration of hydroxide and hydrogen (or hydronium) ions in solution. A solution containing hydrogen (H+ ions) or Hydronium ions (H3O - which is made from the reaction of hydrogen ions with water) indicate a pH lower than 7 or an acidic solution. A solution containing hydroxide ions (OH-) creates a basic solution with a pH greater than 7. It is possible to measure a pH that is greater than the bounds of the scale since the calculation for the scale is based on the negative log of the concentration of hydrogen (or hydronium) ions in the solution. pH=-log[H3O] therefore [H3O] = 10^-pH
