Answer the following parts on acids and bases:<br/><br/><br/>A) Consider the series: CH4, NH3, H2O, HF

Chemistry

Answer the following parts on acids and bases:<br/><br/><br/>A) Consider

the series: CH4, NH3, H2O, HF. HF is a weak acid, H2O is weak acid or base, NH3, is a weak base, but CH4 is neither an acid nor a base. Explain why this makes sense in terms of electrostatic interactions and intramolecular forces. 


B) Ethanol CH3CH2OH is not considered an acid or base, even though there is an H+ and two lone pairs on the oxygen atom. What atoms could be changed on this molecule, other than the OH, to make a compound that would be more acidic?


C) What is the pH of a buffer made by adding 1.0 g of NaHCO3 and 1.0 g of Na2CO3? pKb(CO3 2−) = 3.67
