Question = Is C2F2polar or nonpolar ? Now if you have thought Techiescientist is a Science Blog for students, parents, and teachers. According to the concept of salt, when a neutralization reaction carries out between a strong base and weak acid then the salt is formed which is called a basic salt. Solving the above equation for the acetic acid molarity yields [CH3CO2H] = 1.1 105 M. Some salts are composed of both acidic and basic ions, and so the pH of their solutions will depend on the relative strengths of these two species.

How is it possible to know if a salt will produce a neutral, acidic or basic solution? It is also soluble in ethanol. Explain. Hence, ammonia ( NH 3) is a lewis base. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt's constituent ions. How do you know? To understand this let us first describe what we mean when we call an acid strong or weak. Explain. Wouldn't this happen? In the case of ammonium ions, a solution containing an optimum mix of NH4+ and NH3 acts as an efficient buffer solution. NH4I is a sum of NH4+ and I-, so it can be both acid Let's see how to identify salts as neutral, acidic, or basic. Or would it not because NH4I is a solid and not aqueous? Now that we know the nature of parent acid and base, can you guess what is They have a pH of above 7 and turn red litmus blue. Is a solution with pOH = 3.34 acidic, basic, or neutral? Ammonia ( NH 3) is a Al A few examples of strong acids are HCl, H2SO4, HBr, etc. So, the Ammonium ion(NH4+) undergoes a hydrolysis process and furnishes the protons in water solution, hence, increasing the number of hydrogen ions or H3O+ ions in a solution which ultimately makes the solution acidic or we can say the aqueous solution of ammonium chloride (NH4Cl) is acidic due to hydrolysis of NH4+. Explain. with what we already know. Question: Is calcium oxidean ionic or covalent bond ? bases, when they react, they neutralize each other's effect.
