Aburet containing naoh solution has an initial volume reading of 0.14 ml.
25.00 ml of 0.1000 m hcl is titrated to a phenolphthalein end point, which occurs at a final reading of 27.16 ml naoh. what is the molarity of the naoh titrant?

0.092 M

Explanation:

NaOH(aq) + HCl(aq) > NaCl(aq) + H2O(l)

CA= concentration of acid= 0.1000 M

CB= concentration of base=

VA= volume of acid= 25.00 mL

VB= volume of base= 27.16 mL

NA= number of moles of acid= 1

NB= number of moles of base= 1

CAVA/CBVB= nA/nB

CB= CAVAnB/VBnA

CB= 0.1000 M × 25.00 mL ×1/27.16 mL ×1

CB= 0.092 M

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
