Please give simple, step by step solutions. Thanks!

1) Write the molecular, ionic, and the net ionic equations for the reaction between aqueous potassium carbonate and aqueous lead(II) chloride to form aqueous potassium chloride and a precipitate of lead(II) carbonate.

Molecular equation:

Ionic equation:

Net ionic equation:

2) Show the calculation for determining the mass of NaOH pellets required to prepare 250ml of 0.10 M NaOH.

3) In a titration reaction using sodium hydroxide and KHP, which substance is the proton donor and which is the proton acceptor?

4) In a titration it will reach an endpoint or equivalence point. What is this and what is going on at this point?

##### Solution Summary

This solution is provided in approximately 272 words in an attached .doc file. It writes how to perform each equation, as well as uses moles to calculate mass, discuses proton donors and acceptors, and defines what an equivalence point is.
