It is good practice when preparing a primary standard solution to Select one or more: mix the solution for two minutes after you have added solvent to the volumetric flask. dissolve the solid in the volumetric flask when the bulb is only partially filled with solvent. weigh the solid on an analytical balance. record the volume of solvent required to dissolve the solid.

mark this brainliest lol i need one more.

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.
