Mercury Mercurys atomic emission spectrum is shown in Figure 5.21. Estimate the wavelength of the orange line. What is its frequency? What is the energy of a photon corresponding to the orange line emitted by the mercury atom?
ACIDS AND BASES Acids: produces H+ (which is the same as protons and hydronium ion, H3O+) AND are mostly covalent compounds! H+ + OH- à H2O acid base neutralization The “protics” HCl à H+ Monoprotic ** Compounds that are monoprotic and H2SO 4à 2 H+ Diprotic diprotic are strong acids! H3PO 4à 3 H+ triprotic ** Triprotic are weak acids Ex: H2CO3 à Diprotic weak acid CH 3COOH à monoprotic weak acid Characteristics of acids: Sour Turns blue litmus paper into pink Strong Acids v. Weak acids : 2 converting pH concentration 3 Bases: substances producing OH- in an aqueous solutions AND are ALL ionic compounds Characteristics: Taste is unknown (no one has actuall
