Sodium carbonate is a reagent that may be used to standardize acids. In such a standardization it was found that a .498g sample of sodium carbonate required 23.5mL of a sulfuric acid soln to reach the end pt for the rxn.

Na2CO3(aq) + H2SO4(aq)------->H2O(l) + CO2(g) + Na2SO4(aq)

what is the molarity of the H2SO4?

thanks for anyone's help:)

Suppose your lab instructor inadvertantly gave you a sample of KHP contaminated with NaCl to standardize your NaOH. How would this affect the molarity of your NaOH solution?

I was thinking that since NaOH + NaCl -------> NaCl + NaOH (??), then the molarity would not be affected...but this doesn't seem right...could anyone point me in the right direction? Thank you!!!
