(10pts) Post-Lab Questions Answer the following questions (2pts) Suppose the concentration of the NaOH solution was 0.5 M instead of 0.1 M. Would this titration have required more, less, or the same amount of Nach solution for a complete reaction? Choose (2pts) Suppose you used 0,5 M NaOH to titrate your vinegar sample instead of 0.1 M. What effect does the concentration of base added have on the reliability of the results of your titration? Choose... (2pts) Consider a 0.238 M aqueous solution of sodium hydroxide, NaOH. a. How many grams of NaOH are dissolved in 23.46 ml? (2pts) b. How many individual hydroxide ions (OH) are found in 23.46 mt? (2pts) c. How many moles of sulfuric acid, H2SO4, are neutralized by 23.46 ml. of 0.238 M NaOH(aq) (Hint: begin by writing a balanced equation for this neutralization reaction]
