How do you test scales?
The pH scale is made up of 3 parts:AcidicBasicNeutralThese 3 parts are represented on the scale in different points. The scale is like this:0 1 2 3 4 5 6 7 8 9 10 11 12 13 14A substance with pH between 1-7 is Acidic and on a universal indicator it comes up as the colour red or yellow.7 is Neutral. A neutral is a substance like water it is neither acid or alkaline. It comes up as the colour green.7-14 is Basic. It comes up as the colour blue or purple..Examples:On the scale, if the pH is 1, it is an extremely strong acid this will be deep red.If it is 6, it is an extremely weak acid this will be a yellowish green.if it is 8, it is an extremely weak base and its light blue.If it is a 14, it is an extremely strong alkaline and its dark purple.
