Blue litmus paper is dipped in vinegar. What will be the change in color and why?<\/p>\n\n\n\n
The correct answer and explanation is:<\/strong><\/mark><\/p>\n\n\n\n Correct Answer:<\/strong> Litmus paper is a common chemical indicator used to test the acidity or basicity of a substance. There are two types of litmus paper: blue and red. Blue litmus paper is used to test for acids<\/strong>, while red litmus paper is used to test for bases (alkalis).<\/strong><\/p>\n\n\n\n Vinegar is a weak acid<\/strong>. It contains acetic acid (CH\u2083COOH)<\/strong> as its active ingredient, which releases hydrogen ions (H\u207a) when dissolved in water. This increase in hydrogen ion concentration is what gives vinegar its acidic properties.<\/p>\n\n\n\n When blue litmus paper<\/strong> comes into contact with an acidic solution like vinegar, it undergoes a chemical reaction<\/strong> due to the presence of excess hydrogen ions (H\u207a). These hydrogen ions interact with the dye molecules in the blue litmus paper, altering their structure<\/strong>. As a result, the paper changes from blue to red<\/strong>, indicating that the solution is acidic.<\/p>\n\n\n\n This color change is a qualitative test<\/strong>, meaning it tells us that the substance is acidic but does not measure how acidic it is. Blue litmus turning red is a clear and straightforward sign of an acidic environment with a pH less than 7<\/strong>.<\/p>\n\n\n\n In summary:<\/p>\n\n\n\n This experiment is a basic but effective demonstration of acid-base chemistry often used in schools to teach students about indicators and the pH scale.<\/p>\n","protected":false},"excerpt":{"rendered":" Blue litmus paper is dipped in vinegar.
