A solution of NaOH is titrated with H2SO4. It is found that 20.05 mL of 0.3564 M H2SO4 solution is equivalent to 43.42 mL of NaOH solution. What is the concentration of NaOH?

Answers

Answer 1

Answer:

Answer : The concentration of NaOH is, 0.336 M

Explanation:

To calculate the concentration of base, we use the equation given by neutralization reaction:

$n_1M_1V_1=n_2M_2V_2$

where,

$n_1,M_1\text{ and }V_1$ are the n-factor, molarity and volume of acid which is $H_2SO_4$

$n_2,M_2\text{ and }V_2$ are the n-factor, molarity and volume of base which is NaOH.

We are given:

$n_1=2\nM_1=0.3564M\nV_1=20.05mL\nn_2=1\nM_2=?\nV_2=43.42mL$

Putting values in above equation, we get:

$2* 0.3564M* 20.05mL=1* M_2* 43.42mL$

$M_2=0.336M$

Thus, the concentration of NaOH is, 0.336 M

Mercury is often used as an expansion medium in a thermometer. The Mercury sits in a bulb on the bottom of the thermometer and rises up a thin capillary as the temperature rises. Suppose a Mercury thermometer contains 3.550 g of mercury and has a capillary that is 0.190 mm in diameter. How far does the Mercury rise in the capillary when the temperature changes from 0.0 degrees Celsius to 25.0 degrees Celsius? The density of Mercury at these temperatures is 13.596 g/cm^3 and 13.534 g/cm^3, respectively.
