What should you be careful of when measuring the temperature of a liquid in a beaker
andrezito [222]

The precaution to be taken while measuring the temperature of a liquid in a beaker is applying proper heat balance and taking all the required precautions.

  • A beaker with an open top contains a sample of liquid. It exposes this sample to light.
  • That liquid absorbs the light energy, turning it into heat energy. As a result, the liquid becomes warmer and evaporation is accelerated. As a result, there is less liquid in the beaker.
  • Since it is well known that the surface temperature of a liquid, along with air movement above the liquid surface, is one of the dominant factors affecting evaporation, I want to measure the evaporation rate as a function of surface temperature.
  • This can be done by applying a heat balance.

Rank the following hydroxides in order of increasing aqueous basicity: Al(OH)₃, (OH)₃, In(OH)₃
vovangra [49]

The correct answer is B(OH)3 <AI(OH)3 < In(OH)3.

The metallic character of the group 1 elements first increases from Boron to Aluminium, then decreases from Aluminium to Thallium because of high ionization Enthalpy. Also, the larger size of the ion, the lesser is the ionization of Enthalpy.

Basic nature of the hydroxides of group 13 increases on moving down the group as the electro-positive character of elements increases.

Therefore, the correct order of increasing aqueous basicity is as follows:

B(OH)3 <AI(OH)3 < In(OH)3

What is the basic nature of group 13?

The metallic charecter of the elements affects their fundamental characteristics. The basicity rises as the metallic character does, and vice versa. Therefore, as we move lower in any given group, the atomic radius of the elements increases. Higher radii indicate that it would become increasingly challenging for the nucleus to rule over the electrons in the valency shell. Consequently, there will be a greater inclination for electron release. As a result, the metallic properties will improve, increasing the basicity of the oxides. Therefore, it follows that the basicity of the oxides would rise as we go down in a group.
