Explain why the 0.10 mol L -1 sodium hydroxide solution could not have been prepared by weighing out 1.00g sodium hydroxide, dissolving this in water and making up to 250 ml.
Homework Answers
Given that amount of NaOH = 1.00 g
Number of moles NaOH = amount in g / molar mass
= 1.00 g/ 39.997 g/mol
= 0.0250 moles
Molarity = number of moles / volume in L
=0.0250 moles /250 ml *1 L/1000 ML
= 0.10 mole/ L o r M

A solution is prepared by dissolving 0.23 mol of formic acid and 0.27 mol of sodium formate in water sufficient to yield 1.00 L of solution. The addition of 0.05 mol of NaOH to this buffer solution causes the pH to increase slightly. The pH does not increase drastically because the NaOH reacts with the present in the buffer solution. The K, of formic acid is 1.8 x 10+ A formic acid B. sodium formate C water D. sodium E....
