The pH is a measure of the activity of the ion H+ (the negative logarithm in base 10); the scale is logarithmic.
The acidity range is a part of the pH scale.
It depends on what indicator you are using. Yellow with the bromothymol blue indicator is acidic, yellow with the methyl orange indicator is basic, yellow with the phenol red indicator is acidic and yellow with the universal indicator is acidic.
A pH testing liquid called universal indicator solution is commonly used to test the pH scale. It changes color depending on whether the substance is acidic, neutral, or basic.
A purple solution in universal indicator indicates an alkaline solution with a pH of 14
Each indicator has a specific change of color when the pH is changed.
it indicate the acid and base of the scale
The acidity range is a part of the pH scale.
pH Scale
No, it is an alkali according to the pH scale or pH indicator.
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.
Indicators are substances sensitive to different ranges of pH.
It depends on what indicator you are using. Yellow with the bromothymol blue indicator is acidic, yellow with the methyl orange indicator is basic, yellow with the phenol red indicator is acidic and yellow with the universal indicator is acidic.
A pH testing liquid called universal indicator solution is commonly used to test the pH scale. It changes color depending on whether the substance is acidic, neutral, or basic.
Universal indicator covers a wider pH range compared to litmus indicator, which only detects acidic or basic conditions. Universal indicator provides a more precise indication of the pH level of a solution by producing a range of colors across the pH scale.
Neutral is a word that describes a chemical which turns a universal indicator green. This chemical has a pH equal to 7.0 on the pH scale.
The pH of a solution is measured using universal indicator by adding a few drops of the indicator to the solution and observing the color change. The color of the solution corresponds to the pH level on the universal indicator color scale, which ranges from red (acidic) to purple (neutral) to blue (basic).
Tea is a natural indicator because it shows the pH of something on a scale however it is very basic as you will not get a full colour range.
