Question
Household bleach is an aqueous solution of sodium hypochlorite. What is the chemical formula of sodium hypochlorite ? Is sodium hypochlorite an acid or a base? Prove your answer y chemical reaction between hypochlorite ion and water. You analyze a solution of sodium hypochlorite using a titration analysis like what we did in lab for vinegar. In that analysis, you found that a 25 mL sample of sodium hypochlorite needed 10.25 ml. of 0.0500 M HCl. Write the chemical reaction between HCl and sodium hypochlorite How many grams of sodium hypochlorite are in the bleach sample?Explanation / Answer
Sodium hypochlorite is a chemical compound with the formula NaClO
sodium hypochlorite is base
NaOCl + H2O <--> HOCl + Na + OH-
NaClO + 2 HCl ---> Cl2 + H2O + NaCl.
from balance chemical reaction 1 mole of sodium hypchlorite react with 2 mole of HCl and produce salt, water and Cl2 gas in the 1 ratio.
number of moles of HCl molarity x volume = 0.05 M x 0.01025 L = 0.0005125 moles
no. of moles of NaClO = (0.0005125 / 2 ) moles = 0.00025625 mole
mass of NaClO = (moles x molar mass) = (0.00025625 x 74.44g/mol) = 0.019 g
