The pH scale ranges from 0-14. Universal indicator makes very acidic substances (with a pH of around 0) appear dark red, neutral ones green and very alkaline ones dark blue.

Will strong acids turns universal indicator paper red?
yes strong acids will turn ph paper red
How can hydrochloric acid turn red in color?
Universal Indicator turns concentrated HCl red because Universal Indicator turns strong acids reds.
Do universal indicator acids have a sharp or sweet or blunt taste?
no
What makes universal indicator paper turn red?
acids
What color change does each indicator show to represent acids bases and neutral?
There are far too many indicators to give them all. Litmus is blue in alkali, red in acids and an in-between colour often called claret when neutral. Universal indicator is red in strong acids, blue in strong alkalis and different colours in between depending on the brand.
Would strong acids turn universal indicator paper purple?
nope
Will strong acids turns universal indicator paper red?
yes strong acids will turn ph paper red
How can hydrochloric acid turn red in color?
Universal Indicator turns concentrated HCl red because Universal Indicator turns strong acids reds.
How are acids and bases tested?
universal indicator or litmus paper
What makes universal indicator paper turn red?
acids
Do universal indicator acids have a sharp or sweet or blunt taste?
no
What is universal indicater?
Universal indicator changes colour in acids and alkalis. Its colour shows the strength of an acid or alkali. strong acid= redweak acid= orange / yellowneutral= greenweak alkali= turquoise / bluestrong alkali= deep blue / purple The strength of an acid or alkali is shown on the pH scale of numbers.

How can you tell if food contains acids?
Use universal indicator or litmus paper
Can strong and weak acids be determined by using an indicator?
yes
What acid is universal indicator goes red?
Hi, just looked this up, here's something to show you how universal indicators work:Universal indicator and the pH scaleUniversal indicator is a mixture of several different indicators. Unlike litmus, universal indicator can show us exactly how strongly acidic or alkaline a solution is. This is measured using the pH scale. The pH scale runs from pH 0 to pH 14.Universal indicator has many different colour changes, from red for strong acids to dark purple for strong bases. In the middle, neutral pH 7 is indicated by green.Universal indicator shows how acidic or alkaline a solution isThese are the important points about the pH scale:neutral solutions are pH 7 exactlyacidic solutions have pH values less than 7alkaline solutions have pH values more than 7the closer to pH 0 you go, the more strongly acidic a solution isthe closer to pH 14 you go, the more strongly alkaline a solution is
Can strong and weak acids and strong and weak bases be determined by using an indicator?
yes
