Interpretation:
Solid: Solid is a sample of matter that retains its shape and density when not confined. Stronger forces of attraction exist between atom/ions/ molecules.
Liquid: A liquid is a sample of matter that conforms to shape of container in which acquires a defined surface in the presence of gravity. In this state weaker force exist between atoms/ ions/ molecules.
Gas: A gas is a sample of matter that conforms to the shape of container in which it is placed and acquires whole volume of container.
Negligible forces of attraction exist between atoms/ions/molecules.
Supercritical fluid: Fluid over its critical temperature and pressure exhibiting good solvent power.
Boling point: The boiling point of a substance is the temperature at which the vapour pressure of the liquid equal the pressure surrounding the liquid and liquid change in vapour
Normal point: The normal boiling point of a substance is defined as the temperature at which the vapour pressure of the liquid becomes equal to at the sea level.
Concept introduction:
This is the generic phase diagram. This graph show phase change as a function of temperature and pressure.
To determine:
Argon has a normal boiling point at and a melting point of its critical temperature is and critical pressure is atm. It has triple point at and . Sketch the phase diagram and find out which has greater density solid argon or liquid argon.

- The 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.
