Determine the volume at the equivalence point if a 0.100 m naoh(aq) solution is used to titrate the following acidic solutions: (a) 50.0 ml of 0.200 m hbr(aq) (b) 30.0 ml of 0.150 m hno3(aq)

a) NaOH volume at the equivalence point is 100 ml.

b) NaOH volume at the equivalence point is 45 ml.

Explanation:

To calculate the concentration of acid, we use the equation given y neutralization reaction:

where,

are the n-factor, molarity and volume of acid.

are the n-factor, molarity and volume of base

a) If a 0.100 M NaOH (aq) solution is used to titrated with 50.0 mL of 0.200 M HBr(aq).

We are given:

Putting values in above equation, we get:

b) If a 0.100 M NaOH (aq) solution is used to titrated with 30.0 mL of 0.150 M (aq).

We are given:

Putting values in above equation, we get:

i sometimes feel that way too. i feel that i should hurt someone because they hurt me, but i wouldnt do it. that would make things so much worse i have so much experience with this stuff

explanation:

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
