Without detailed calculation and RICE table, determine whether the following solutions are acidic or basic, buffer or not buffer. Explain your answers by identifying the major species and the dominate chemical reaction. (a) 1M Nacl + 1M HCl in equal amounts (b) 1M NH,Cl + 1M NH3 in equal amounts (c) 1M Na2C2O4 + 1M HCl in equal amounts (d) 2M H3PO4 + 3M NAOH in equal amounts
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.
Since we only answer up to 3 sub-parts, we’ll answer the first 3. Please resubmit the question and specify the other subparts (up to 3) you’d like to get answered.
A solution is said to be acidic, when the pH of the solution is less than 7 and it donates protons to the solution.
A solution is said to be basic, when the pH of the solution is more than 7 and it accepts protons from the solution.
A solution is said to be neutral, when the pH of the solution is equal to 7 and it accepts and donates equal amount of protons in the solution.
An acidic buffer is defined as an aqueous solution that consists of a mixture of a weak acid and its conjugate base.
A basic buffer is defined as an aqueous solution that consists of a mixture of a weak base and its conjugate acid.
The pH of the buffer solution changes to a very little amount when a small quantity of strong base or acid is added to it.
