this is because it is more specific(Y):)
Universal indicator can show a wider range of pH levels compared to litmus indicator, which can only indicate acidic or basic solutions. Universal indicator provides a full spectrum of colors corresponding to different pH values, making it more precise and versatile for measuring pH levels in various solutions.
It can only see if it is acidic or not but not telling you how acidic it is unlike the universal indicator.
Phenolphthalein Litmus Red Litmus Blue Universal Indicator -> Most Common Methyl Orange :)
universal indicator or litmus paper
With a universal indicator or with litmus paper.
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.
No totally different, universal indicator is a mixture of chemical which shows the precise p.H of a substance, blue litmus paper reveals whether the substance is acidic or alkaline.
Litmus paper or universal indicator are the best ways.
Use universal indicator or litmus paper
Just test it with universal litmus paper or universal indicator(liquid)
If you are testing with Universal Indicator or the Litmus Test it will turn red.
Universal indicator gives you an indication of the pH of the acid (i.e its 'strength') While both sulfuric acid and vinegar would turn litmus paper red, sulfuric acid would turn universal indicator red, pH of 1, while vinegar would turn it yellow-orange, pH of 4.
