Question

Calculate the molarity of h after 25 ml of 0.025 m koh was added. Remember, the volume has changed and is now the sum of the two mixed volumes?

Answer 1

Explanation:

Given

initial volume
`V_1=25\ ml`

initially Molarity
`c_1=0.025\ m\ of\ KOH`

suppose V liter is added to the mixture

To calculate the molarity of diluted solution

`c_1V_1=c_2V_2`

final volume
`V_2=V+25`

`0.025* 25=c_2* (V+25)`

`c_2=(0.025* 25)/(V+25)`

`c_2=(0.625)/(V+25)\ m`
