The pH value is an indication of the acidity/alkalinity of a solution. More precisely, the pH value is a representation of the concentration of hydrogen cations (hydronium ions) in a solution.

What can measure pH?

pH can be measured using a pH meter, pH paper, or pH indicator solutions. These tools detect the acidity or basicity of a solution by measuring the concentration of hydrogen ions present.


The pH number is an indicator for?

Hardness


What does pH indicator?

p = -log H= concentration of hydrogen in solution (H+) therefore, pH= -log [H+] or [H+] = 10-pH


How does the concentration of H affect the number on the pH scale?

The meaning of a higher H+ concentration is a low pH.


How is acidic concentration of a solution determined?

The acidic concentration of a solution is typically determined using a pH meter or pH indicator paper. The pH value indicates the concentration of hydrogen ions in the solution, with lower pH values indicating higher acidity. Titration with a standardized base solution can also be used to determine the acidic concentration of a solution.


What factor determines the pH at the equivalence point?

the concentration of hydrogen ions - H+


How can one determine the pH of a weak acid?

To determine the pH of a weak acid, you can use a pH meter or pH indicator paper. Alternatively, you can calculate the pH using the concentration of the weak acid and its dissociation constant.


How can one determine the pH of a weak base?

To determine the pH of a weak base, you can use a pH meter or pH indicator paper. Alternatively, you can calculate the pH using the concentration of the weak base and its equilibrium constant.


When the concentration of hydrogen ions increases the pH number of a solution?

When the concentration of hydrogen ions increases, the pH number of a solution decreases. pH is a measure of the acidity or basicity of a solution, with lower pH values indicating higher acidity.


How are universal indicator and the pH scale linked?

Universal indicator is a solution composed of several different indicators, each of which changes color at different pH levels. The pH scale is a way to measure the acidity or alkalinity of a substance based on its concentration of hydrogen ions. Universal indicator's color change corresponds to different pH levels, making it a useful tool for determining the pH of a substance.


What is the pH number of phosphorus chloride?

pH doesn't work that way. The pH depends on the concentration as well as the substance; it's meaningless to talk about the pH of a substance without specifying a concentration as well.


How are indicators used to determine pH?

Indicators are substances that change color depending on the acidity or basicity of a solution. By adding an indicator to a solution of unknown pH and observing the color change, one can determine the approximate pH of the solution based on the color of the indicator at that pH range. This color change is due to the indicator's ability to undergo a reversible chemical reaction that is sensitive to changes in hydrogen ion concentration.
