Testing pH of Household Substances

"Please tell me, is it first checked with litmus paper whether a substance is an acid or a base, and then the resulting color is matched with the pH scale?" 😮‍💨😮‍💨

Yes, you can use litmus paper to get an initial indication of whether a substance is acidic or basic, but litmus paper only shows whether a substance is an acid or a base - it does not give the precise pH. Here's how it works: Litmus Paper Test: Red litmus paper turns blue in the presence of a base. Blue litmus paper turns red in the presence of an acid. If there's no color change, the substance is likely neutral (pH ~7). Using the pH Scale: If you need a more accurate pH measurement, you use pH paper or a pH meter instead of litmus paper. pH paper changes color across a range of values, which you can match against a color chart to determine the exact pH. So, litmus paper can quickly indicate whether a substance is acidic or basic, but it does not directly correlate to the pH scale. For precise pH values, you would need a pH-specific testing method.
