Question

Write equations showing: the ionization of nitric acid in water ionization of solid potassium hydroxide (KOH) in water. potassium nitrate a component of black powder gunpowder some fertilizers, was obtained from the late Middle Age through the nineteenth century by precipitation from urine. Commonly called saltpeter, it can be prepared by the reaction of nitric acid with potassium hydroxide. Write the equation for this neutralization reaction. Classify- the three aqueous solutions shown below as acidic, basic, or neutral. (For clarity, water molecules arc not shown.) What is the conjugate base HBr ? What is the conjugate acid of OH ? Please circic the correct answer: Which of the following is NOT a property of a base? Turns litmus paper red Proton acceptor Feels slippery A solution with a pH of 4 can be described as basic. acidic. neutral. D. strongly baste. Which of the following statement best describes oxidation and reduction reactions'' A An oxidation reaction must occur when a reduction reaction occurs. The reactions occur only between two metals. Half electrons arc transferred in hall reactions. The reactions always involve oxygen. Tastes bitter
