Check it out! If the strip stays the same colour, it is proven that the two substances have been neutralised. An indicator such as methyl orange or litmus is put into the base. You can print the table out and tick off whether each substance is acidic, basic or neutral. Acidic substances include vinegar, lemon juice and battery acid. Thanks so much for the pin, you have really brightened my day with that! Dip your strips of litmus into the rainwater. This website and its content is subject to our Terms and If it turns blue, that substance is a base. I am sure the litmus paper will turn out perfectly for you. You can test whether the rainwater in your area is slightly acidic. You simply dip the paper in your substance, and it will change colour depending on whether it is acidic or basic. Some interesting kitchen science experiments are the best way to get children involved in science. Dip a strip of litmus paper into it. If it stays the same, that substance is neutral. Neutral litmus paper is purple. If it turns blue, that substance is a base. However, it would be nice to have some examples or other reasons why and how one can use these strips in the household for everyday causes. Primarily aimed at the upper end of KS2 but I have used this with Year 4 and Year 7 as all files can be modified to suit different ages and abilities. If you cannot find any blotting paper in the shops, you can buy blotting paper on Amazon. Primarily aimed at the upper end of KS2 but I have used this with Year 4 and Year 7 as all files can be modified to suit different ages and abilities. Here's how: The red cabbage you used can be used as pH indicator. Susan W (author) from The British Isles, Europe on May 26, 2015: tirelesstraveler - Thanks for the great comments! This way the two substances become neutralised. Yes, this would be a good science project to do, and children can learn about acids and bases and become interested in science.

Strain the red cabbage from the solution. For a great pH paper experiment, check out the end of this post! Another method to determine whether a solution is an acid or base is to use litmus paper. It is red or pink in acids (pH < 7), purple in neutral solutions and ranges from blue to green to yellow in alkaline solutions (pH > 7). A great way of showing this concept in action. The main use of litmus is to test whether a solution is acidic or basic.Light Blue litmus paper turns red under acidic conditions and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F). You would have to have home grown tecniques.
