Hello, I'm 1997kB. An edit you recently made to Iodine clock reaction seemed to be a test and has been removed. If you want more practice editing, the sandbox is the best place to do so. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thank you. &#8208;&#8208;1997kB (talk) 09:05, 15 September 2020 (UTC)
