How many liters of 0.200 m sodium hydroxide do you need to titrate 0.400 l of a 0.100 m diprotic acid to the equivalence point? 0.400 l naoh

Explanation:

Since, the acid is diprotic, you have that 1 mol of it releases 2 mol of hydrogen ions, H⁺.

Determine the number of moles of acid, using the molarity definition:

And the number of moles of H⁺ ions equals 2 × 0.0400 mol = 0.0800 mol

At the equivalence point of the titration the number of moles of H⁺ from the acid equals the number of moles of OH⁻ from the base.

Since, sodium hydroxide ionizes in a ratio 1 : 1 (1 mol of NaOH / 1 mol OH⁻), the number of moles of NaOH is equal to 0.0800 mol

And now you use the molarity definition for the 0.200 M sodium hydroxide solution:

That is the 0.400 liter of 0.200 M sodium hydroxide.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
