NAOH required = 23.20 mL; HCl required = 2.675 mL. Ifeach ml of HCI is equivalent (=) to 0.01600 g of Na20, what volume of 6.00 NNaOH must be added to 500 mL of above NaOH to bring it to 0.5000N?3.4.A sample of processed meat scrap weighing 4.000 g is digested withconcentrated H2SO4 and Hg(catalyst) until the N present has been converted toNH&HSO4. This is treated with excess NaOH, and the liberated NH3 is caught in a100-mL of H2SO4 ( 1mL = 0.01860 g Na20). The excess acid requires 57.60 mL ofNaOH ( 1mL = 0.12660 g potassium acid phthalate, KHC8H4O4). Calculate thepercentage protein in the meat scrapA 1.2 g sample of mixture of NaOH and NA2CO3 containing inert impurities sdissolved and titrated cold with 0.5N HCI. With phenolphthalein as indicator thesolution turns colorless after the addition of 30.0 mL of the acid. Methyl orange isthen added and 12 mL more of the acid is required before this indicatorchanges color. What is the percentage of NaOH and of Na2CO3 in the sample ?5.
