50.0 ml of 0.010m naoh was titrated with 0.50m hcl using a dropper pipet. if the average drop from the pipet has a volume of 0.0
creativ13 [48]

25 drops of acid is required to neutralize the 50.0 ml of 0.010m of NaOH in the experiment.

The equation of the reaction is;

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

We can use the titration formula;

CAVA/CBVB = NA/NB

CA= concentration of acid

VA = volume of acid

CB = concentration of base

VB = volume of base

NA = number of moles of acid

NB = number of moles of base

CB = 0.010 M

VB = 50.0 ml

CA = 0.50 M

VA = ?

NA = 1

NB = 1

Substituting values;

CAVANB = CBVBNA

VA =  0.010 ×  50.0 × 1/ 0.50 × 1

VA = 1 ml

Since the total volume of acid used is 1 ml and each drop contains 0.040 ml

The number of drops required is 1ml/0.040 ml = 25 drops

alisha [4.7K]

The scientific instruments used to heat water to 85 degree Celsius has been graduated cylinder, beaker, thermometer, and hot plate. Thus, option B is correct.

Scientific equipments have been defined as the instruments and glassware that has been used in the scientific study and experimentation.

<h3>Equipments for heating the water</h3>

The water has been heated to the temperature of 85 degrees Celsius. The temperature has to be monitored thus, a thermometer has been used.

The water has been measured to be 1 L, thus the graduated cylinder, and beaker has been used for the measurement and heating of water.

The heat has been provided to the beaker by placing it on a hot plate.

Thus, the scientific instruments used to heat water to 85 degree Celsius has been graduated cylinder, beaker, thermometer, and hot plate. Thus, option B is correct.
