calculate the number of grams of NaOH per 100ml to give a pH8.0solution if pure water at pH7.0 is used in the experiment. Repeatthis calculation for a pH6.0 solution using HCl.
Comment on how this or would not explain the fact that distilledand tap water are not exactly at a pH value of 7.000
Do the Ph values for more dilute solutions approach the ph ofdistilled water? what would you expect to happen if you continuedto dilute these samples even further? explain your answer.
what would you predict if you compared the ph values in adilution experiment for a strong acid such as HCl and a weak acidsuch as acetic acid. do the ph values increase at the samerate?
what would you expect to happen if you combined 10.0 ml of 10^-2M acetic acid and 5.0 ml of 10^-2 M sodium hydroxide? what would bethe concentration of acetic acid and sodium acetate in thissolution? would you expect this solution to be a buffer? EXPLAINYOUR PREDICTION.
