What volume of 0.140M HCl is required for the complete neutralization of 1.40g of NaHCO3 (sodium bicarbonate)? What volume of 0.200M HCl is required for the complete neutralization of 1.30g of Na2CO3 (sodium carbonate)? A sample of NaOH (sodium hydroxide) contains a small amount of Na2CO3 (sodium carbonate). For titration to the phenolphthalein endpoint, 0.150g of this sample requires 23.98 mL of 0.100 M HCl. An additional 0.700 mL of 0.100 M HCl is required to reach the methyl orange...
