pH paper Merck art. 9565 become brown in an acid.
universal indicator solution can be used to determine acid or base at the same time . Its changes its colour and helps in determing the chwmical property
This is because the toothpaste has some amount of acid or alkaline in it .
No
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.
Any base neutralizes an acid. An example of this is vinegar (acetic acid) and baking soda (a basic salt). Another example is, Hydrochloric acid and sodium hydroxide (a base). These reactions are described by the following chemical equations: HC2H3O2 + NaHCO3 ===> NaC2H3O2 + H2O + CO2 HCl + NaOH ===> NaCl + H2O
