You're out exploring a swamp collecting data on how climate change affects N20 emissions from wetlands. You stomp on the swampy soil and light a match---FIRE. That lets you know the soils below is harboring methane (CH4) gas. Knowing this, do you expect much nitrate in these soils? (Yes or No) You dig 20 cm deep below the muck and you find clayey soils that are mottled with gley colors. Do you expect this soil to contain a lot of manganese oxides or iron oxides? (Yes or No)

Solutions

Solutions can be considered as homogeneous mixtures which contain two or more than two chemical substances. The chemical substance which is the greater part is defined as solvent. And the chemical substance that is dissolved in a solvent is referred to as solute. Solution chemistry plays an important role in chemistry since it supports many commercial applications of solutions.
