NaCN (sodium cyanide) is made from a strong base NaOH and weak acid HCN so it is a strong base.

In the question HNO2 is a weak acid and NaNO2 is it's salt. So it will form a buffer Solution. NaOH is a strong base and NaCl is its salt. So this mixture is not a buffer Solution.

All acids under the Lowry-Bronsted definition, yes. Under the Lewis definition, metal ions can be acids, so obviously for them the answer is no. The most common bases are metal hydroxides, which are mostly ionic, like NaOH. Some weak bases (like ammonia) are covalent.

1 Expert Answer KCN is the salt of a strong base (KOH) and a weak acid (HCN), and thus the salt in aqueous solution will have a basic pH.

- Salts of weak bases and strong acids: pH less than 7 (acidic). - Salts from strong bases and weak acids: pH greater than 7 (alkaline). Based on these rules, the solution of Mg(NO3)2 dissolved in water is Netural.

Ammonium is a weak acid, but the conjugate base of ammonium is ammonia, NH3, which is a strong base. NH3 is a weak base. NH2-, known as the amide ion is a very powerful base.

Sometimes the hardest part of a calculation is deciding whether the compound is an acid or a base. Consider sodium bicarbonate, for example, which dissolves in water to give the bicarbonate ion. In theory, the bicarbonate ion can act as both a Brnsted acid and a Brnsted base toward water.

A strong base is one that completely dissociates (breaks apart) in solution. In the case of NaOH (sodium hydroxide), the compound breaks apart into Na+ and OH- ions completely. This makes NaOH a strong base.

Sodium nitrate is the salt that would be produced in the reaction of sodium hydroxide, a strong base, and nitric acid, a strong acid. As such, NaNO3 is neither an acid nor a base.

All acids beginning with the prefix „hydro“ are otherwise known as binary acids. HCl, which contains the anion chloride, is called hydrochloric acid. HCN, which contains the anion cyanide, is called hydrocyanic acid. ... Since all these acids have the same cation, H+, we don't need to name the cation.

Indeed, sodium amide does deprotonate terminal alkynes (it can be used for elimination reactions, too). This is possible because the NH₂¯ anion is the conjugate base of Ammonia (NH₃) and, as a general acid-base principle, the weaker the acid, the stronger its conjugate base (Conjugate acid).

Vinegar or Acetic Acid has the chemical formula CH3COOH . Baking soda is a base also known as Sodium Bicarbonate and has the chemical formula ‎NaHCO3 . During this reaction the products are sodium acetate ( C2H3NaO2 ). Sodium acetate is made of 1 sodium ion, 2 carbon atoms, 3 hydrogen atoms, and 2 oxygen atoms.

Why is NaOCH3 a strong nuc and strong base? These are strong nucleophiles because it's attached to a metallic group Na+ so it's automatically a negative anion.

For example, NH4Br is the salt of a weak base (NH3) and a strong acid (HBr), so the salt is acidic. ... This means that two of the solutions are basic (NH3 and NaF), one solution is neutral (NaCl), and the other is acidic (NH4Br).

According to the Brønsted-Lowry acid base-theory, an acid is a proton (hydrogen ion, H+ ) donator, and a base is a proton (hydrogen ion, H+ ) acceptor. Ammonia is the hydrogen ion acceptor, and is therefore a base, and water is the hydrogen ion donor, and is therefore an acid.
