Acids have pH below 7 and are sour in taste. We can taste mild acids but strong acids are tested by indicators .acids turns blue litmus to red. Base have pH above 7 and are bitter in taste these have soapy texture. And base turns red litmus to blue. ...
Bases change the colors of indicators (litmus turns from red to blue) and they neutralize acids. Hence, bases are considered the chemical opposite of acids. Most common acid-base reactions take place in water solutions (commonly referred to as aqueous solutions ). One of the earliest ...
In case of acid solution (PH<4.5), blue litmus paper turns red; The pH value of the solution is between 4.5-8.0, and the red litmus and blue litmus paper will not change color. Package Included 2 x boxes (200 strips in total) ...
It turns blue litmus red. It reacts with many metals (e.g., with zinc), releasing hydrogen gas, H2, and forming the sulfate of the metal. It reacts with most hydroxides and oxides, with some carbonates and sulfides, and with some salts. Since it is dibasic (i.e., it has two ...
What does the litmus test tell about stability of sulfurous acid? The litmus test can help determine if sulfurous acid is an acid or a base. If sulfurous acid turns blue litmus paper red, it indicates that it is an acid. This test does not provide direct information about the stabilit...
“strong acid” category, and a good electrolyte. It is highly ionized, much of the heat released in dilution coming from hydration of the hydrogen ions. The dilute acid has most of the properties of common strong acids. It turns blue litmus red. It reacts with many metals (e.g., ...

Step-by-Step Solution:1. Understanding Litmus Paper: Litmus paper is a natural indicator used to test the acidity or basicity of a solution. It comes in two colors: blue and red. Blue litmus paper is used to te
In many ways, litmus paper is the perfect scientific sensor. It is cheap, requires no power or skill to use and yields instant results. Blue paper turns red in acids. Red paper turns blue in alkalis. And that is all you need to know. In the real world, though, things are a bit ...
