9. (1.5') Experiments in AFM requires the use of clean metallic surfaces for substrates. A simple way to test if an evaporated metal film is free from atmospheric contamination (due to adsorption of hydrocarbons from atmosphere) is to pace a drop of pure water on the metal and observe the equilibrium shape of the water drop. Which situation pictured above would indicated the cleanest metal surface?
Ionic Equilibrium
Chemical equilibrium and ionic equilibrium are two major concepts in chemistry. Ionic equilibrium deals with the equilibrium involved in an ionization process while chemical equilibrium deals with the equilibrium during a chemical change. Ionic equilibrium is established between the ions and unionized species in a system. Understanding the concept of ionic equilibrium is very important to answer the questions related to certain chemical reactions in chemistry.
Arrhenius Acid
Arrhenius acid act as a good electrolyte as it dissociates to its respective ions in the aqueous solutions. Keeping it similar to the general acid properties, Arrhenius acid also neutralizes bases and turns litmus paper into red.
Bronsted Lowry Base In Inorganic Chemistry
Bronsted-Lowry base in inorganic chemistry is any chemical substance that can accept a proton from the other chemical substance it is reacting with.
I need the correct option in the attached question. It would be great if you can explain it. Thanks!
