<span>Electron microscopes can magnify objects to 10,000,000x the smallest object that can be viewed is larger than an electron. Electron microscopes can improve the resolution that is achieved by light microscopes. Entire cells can be viewed and their components.</span>
I believe an aqueous solution is made up of ions dissociated in solution. An aqueous solution is a solution in which water acts as a solvent. For example a solution sodium chloride in water is shown as Na+(aq) + Cl-(aq). Most acids and bases exists in aqueous solution form.
