(a)
Interpretation:
The level of mercury on decreasing the temperature from
Concept introduction:
The change in temperature with change in pressure can be represented as follows:
Here, P is pressure, T is temperature and 1 and 2 is initial and final values.
(b)
Interpretation:
The approximate level of the mercury needs to be determined for the given conditions.
Concept introduction:
The manometric unit of presusre is mm Hg. It is defined as extra pressure that is generated by the column of mercury wich is 1 mm high and it is equal to 133.322 pascals. It is not the SI unit of pressure. The reading from a mercury column can be converted into other units of pressure by multiplying the height difference between two mercury levels by denisty of the mercury and gravitational acceleration.
(c)
Interpretation:
The approximate level of the mercury when the stopcock in (2) drawing is opened needs to be determined.

- Give detailed Solution with explanation needed with structures. don't give Ai generated solution. avoid handwritten Solutionarrow_forwardThe acid-base indicator HX undergoes the following reaction in a dilute aqueous solution: HX (color 1) H+ + X- (color 2). The following absorbance data were obtained for a 0.00035 M solution of HX in 0.1 M NaOH and 0.1 M HCI. Measurements were made at wavelengths of 450 nm and 620 nm using a 1.0 cm glass cuvette. 450 620 A(460 nm) A(630 nm) 0.1 M NaOH 0.1 M HCI 0.065 0.435 0.895 0.150 In the 0.1M NaOH solution, the indicator will be almost 100% in the X- form, while in 0.1M HCI, the indicator will be nearly 100% protonated (HX). Calculate the acid dissociation constant for the indicator if a pH=5 buffer solution containing a very small amount of indicator exhibits an absorbance of 0.567 at 450 nm and 0.395 at 620 nm (measured in a 1 cm glass cuvette).arrow_forwardShow work...give the name of the given compound.
