4、universal pH indicator paper 1-14 What is pH? pH is simply a scale for expressing the acidity or alkalinity of asubstance. The scale ranges from 0 to 14.A 7 is considered neutralwhile values less than 7 are more acidic, and values above 7 aremore alkaline。
Red Cabbage Indicator Scale Universal Indicator pH colours Notice that the colours for acids and alkalis are different when using a universal indicator. Universal Indicator pH Scale Results When using the red cabbage indicator, the colour of the liquid will change from purple to red if it is an ...
So, the pH scale is developed to measure the hydrogen ion concentration. Its values range from 0 to 14, which are known as pH values. So, we can say that the pH value is a number that indicates the acidic and basic nature of a solution. Limitations of pH scale There are somelimitatio...
