Neither K+ nor ClO4- has any tendency to donate or accept a proton in dilute aqueous solutions. My thesis aimed to study dynamic agrivoltaic systems, in my case in arboriculture. When the pH values were measured, the solutions showed different pH values: One of the things that I have been learning to make is Irish brown bread, a rather tasty version of a soda bread. The bread is called a soda bread because it has baking soda (sodium bicarbonate) in it. But you have to compare the Ka and Kb for these species before making a judgement! In essence, you can go from an acid to its conjugate base by removing a proton, and from the conjugate base to the original acid by adding a proton. The decrease in electron density weakens the OH bonds in the water molecules and makes it easier for them to lose a proton. Legal. * Answer = AsH3 ( Arsine ) is Polar What is polarand non-polar?
