Without first writing a full molecular or ionic equation, write the net ionic equations for any precipitation reactions that occur when aqueous solutions of the following compounds are mixed. If no reaction occurs, so indicate. (Omit states-of-matter in your answer. If no reaction occurs, enter "NONE".)
A) iron(III) nitrate and sodium carbonate
B) copper(II) sulfate and sodium sulfide
C) lithium chloride and lead(II) nitrate
D) gold(III) chloride and sodium hydroxide
A 10.0 mL aliquot of this weak acid solution was titrated with a 0.0498 M NaOH solution. The equivalence point was reached by adding 11.62 ml of NaOH from the buret. What is the molar mass of this unknown acid?
