What is the pOH of a KOH solution that has [OH− ] = 5.81 × 10−3 M?

The pOH of the KOH solution is 2, 24.

Explanation:

The pOH is a measure of the concentration of OH (hydroxyl) ions in the solution.

The pOH is calculated as :

pOH = -log (OH-)= -log ( 5.81 × 10−3 M)= 2,24.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.
