Relative to the number of strong acids, there are fewer number of strong bases and most are alkali hydroxides. Calcium hydroxide is considered a strong base, because it is completely, almost completely, ionized. However, the solubility of calcium hydroxide is very low. When \(\ce{Ca(OH)2}\) dissolves in water, the ionization reaction is as follows: Weak bases:- Magnesium hydroxide as antacids, ammonia as rocket fuel, aluminium hydroxide as deodorant, etc. Strong bases:- Alkaline batteries, lubricating grease, soap, baking soda, etc. Pure water can act as a poor base and a poor acid. Some other common examples of bases are Vegetables and fruits such as watermelon, kiwi, etc. Hence, it is a weak base among all given hydroxide compounds. Al(OH) 3+H 2O→Al(OH) 4−+H +. Explanation for incorrect options: NaCl dissociates completely giving Na + and Cl − ions and considered as strong base. Similarly, KOH and Ca(OH 2) also releases OH − in the solution hence making them a strong base. Final answer: Option C. As sodium hydroxide is a very strong base, its conjugate acid is supposed to be weak, and water is a weak acid only. The conjugate acid of NaOH is Water ie; H2O The Conjugate acid-base concept determines the relative strength of acid and base. Ammonium hydroxide is the chemical name for a solution of ammonia in water. A familiar example of ammonium hydroxide is household ammonia, which is a solution of 5-10% ammonia. Ammonium hydroxide is a weak base. It is a clear liquid with a distinctive pungent, fishy odor. Verified by Toppr. The correct option is D it is only partially ionised. Solution:- (D) it is only partially ionised. N H 4OH is a weak base because it partially ionised in water and produce a small amount of hydroxide ions (OH −). N H 4OH ⇌ N H 4+ +OH −. Was this answer helpful? The solution pH is then calculated using the concentration of hydroxide ion: n (OH Acid-base indicators are either weak organic acids or weak organic bases. The equilibrium in a solution of the acid-base indicator methyl orange, a weak acid, can be represented by an equation in which we use HIn as a simple representation for the complex An acid-base extraction is a type of liquid-liquid extraction. It typically involves different solubility levels in water and an organic solvent. The organic solvent may be any carbon-based liqiuid that does not dissolve very well in water; common ones are ether, ethyl acetate, or dichloromethane. Acid-base extraction is typically used to A base is a substance that can accept hydrogen ions ([latex]\text{H}^+[/latex]) or, more generally, donate a pair of valence electrons. A weak base is a chemical base that does not ionize fully in an aqueous solution. As Brønsted-Lowry bases are proton acceptors, a weak base may also be defined as a chemical base with incomplete protonation. Sulphuric acid is a strong acid, while zinc hydroxide is a weak base, hence, the solution is acidic in nature. Question 8: An aqueous solution of ammonium acetate, neutral in nature. Why? Answer: Ammonium acetate, when dissolved in water is hydrolysed to form ammonium hydroxide and acetic acid. Ammonium hydroxide and acetic acid both are weak ZgQ6HAy.
