Jul 15, 2023 · If we raise the temperature somewhat, all the KCl will dissolve, but on cooling to 25°C again, the extra 0.5 g KC1 will precipitate, leaving exactly 35.5 g of the salt dissolved. We describe this phenomenon by saying that at 25°C the solubility of KCl in H 2 O is 35.5 g KC1 per 100 g H 2 O. Oct 24, 2012 · See tutors like this. Since KCl is a neutral molecule, the sum of the oxidation states of the atoms equals zero. We know that potassium (K) has an oxidation of +1 since it is a group 1 element. So, K +1 Cl -1 ===> KCl 0 OR KCl. Thus, the charge on potassium (K) in KCl is +1. Upvote • 2 Downvote. Jul 21, 2023 · DN Store.
