In an attempt to measure the effects of acid rain, researchers measured the pH (7 is neutral and values below 7 are acidic) of water collected from rain in Gurabo, Puerto Rico. 5.40 5.37 5.38 4.63 5.39 3.74 3.71 4.96 4.64 5.12 5.65 5.36 4.16 5.87 4.57 4.62 5.48 4.57 4.57 4.53 4.82 4.52 4.69 4.32 3.98 5.70 4.35 3.98 5.68 3.44 5.04 4.67 4.51 4.34 4.16 4.64 5.12 3.74 4.64 5.59 Draw the correct histogram. Many scientists consider rain with pH below 5.3 to be acid rain. What percentage of these samples could be considered as acid rain? Note: You may MS Excel, but you must submit the file

Ph and pOh of 0.020m HNO3​

Calculate the pH of a 0.123 M solution of ethylenediamine (H₂NCH₂CH₂NH₂). The pKą values for the acidic form of ethylenediamine (H3NCH₂CH₂NH³) are 6.848 (pKal) and 9.928 (pKa2). pH = Calculate the concentration of each form of ethylenediamine in this solution at equilibrium. [H₂NCH₂CH₂NH₂] : = [H₂NCH₂CH₂NH3] = M M
