A scientist places a pH meter in a sample of concentrated potassium hydroxide (KHO) . the scientist slowly adds nitric acid (HNO) to the KHO and monitors the pH. describe how the pH and hydronium ion concentration will change in the solution as the acid is added. PLEASE HELP ASA ALSO I HOPE ANYONE WHO SEES THIS IS HAVING AN AMAZING DAY .. REMEMBER TO SMILE !! ❤️❤️❤️

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.
