CHY 104 Lecture Notes - Lecture 9: Hydrogen Iodide, Conjugate Acid, Scientific Notation
Document Summary
An arrhenius acid is any substance that provides hydrogen ions, h+, when dissolved in water. An arrhenius base is any substance that provides hydroxide ions, oh-, when dissolved in water. Hno3 is an acid: hno3(aq) h+ (aq) + no3. Koh is a base: koh(aq) k+ (aq) + oh- (aq) A br nsted acid is any hydrogen-containing substance that is capable of donating a proton (h+) to another substance. A br nsted base is any substance capable of accepting a proton from another substance. In this reaction, hno2 behaves as a br nsted acid by donating a proton to the h2o. The h2o behaves as a br nsted base by accepting the proton. Example of a br nsted acid & base (continued) The reaction was written using a double arrow that points to both the right and the left, signifying that the reaction can go in either direction and establish an equilibrium.
