pH for Bases
pH of bases or basic solutions is greater than 7. When a solution has a pH greater than 7, it is referred to as the basic solution. A solution with a pH of 12 will, for example, be basic in nature or a base. It should be remembered that the higher the pH of a solution, the more basic it is. A solution with pH 14, for example, is significantly more basic than a solution with pH 11. In other words, a pH 14 solution will be a much stronger base than an acid with a pH of 11. Strong bases are often defined as solutions with a pH of 11, 12, 13, or 14. Weak bases are defined as solutions with pH values of 8, 9, and 10. The pH of very basic compounds is extremely high. In fact, the stronger the base, the higher the pH.
Since all solutions with a pH greater than 7 are basic in nature, they turn red litmus blue. In addition, they make the phenolphthalein indicator pink.
What is a Universal Indicator?
Universal Indicators in Chemistry is defined as a chemical indicator that is used to check the pH for a wide range of solutions. In general, when we use any chemical indicator it is used to identify the acid or base but does not cover the range of acid and base it also does not cover the strength of the acid and base. In that case, we use a universal indicator as it also tells the acidic or basic strength of the solution.
Here in this article, we will learn about Universal Indicators, universal indicator colour charts, universal indicator examples and others in detail.
