I'm in 7th grade and I have a science fair project due around the 25th of January. My project was investigating on which type of salts contain iodine. I tested kosher salt, sea salt, table salt, rock salt, crystalline sea salt, and Himalayan pink salt. I used a mixture of white vinegar, 3% hydrogen peroxide, and laundry starch solution and added it to each salt. Each salt had water added to it. A reaction occurred with the table salt and sea salt, where the salt and water mixture turned a dark purple color, meaning it contained iodine. I can't think of a creative title to draw students to my project and I could really use some help.
Thanks!
