Hello, I'm RainbowLover334148. I wanted to let you know that one or more of your recent contributions to Sulfuric acid have been undone because they appeared to be promotional. Advertising and using Wikipedia as a "soapbox" are against Wikipedia policy and not permitted; Wikipedia articles should be written objectively, using independent sources, and from a neutral perspective. Take a look at the welcome page to learn more about Wikipedia. Thank you. RainbowLover334148 (talk) 12:14, 13 November 2021 (UTC)

Hello, I'm Kpgjhpjm. I wanted to let you know that one or more external links you added to Sodium chloride have been removed because they seemed to be inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links. Thank you.
