An acidic solution can be formed when a non-metal oxide is dissolved in water. For example, magnesium oxide dissolves to form alkaline solutions. Sulfur dioxide and nitrogen dioxide however, will dissolve to form acidic solutions.
What compound dissolves in water to form an acidic solution?
Nonmetal oxides dissolve in water to form acids. CO 2 dissolves in water to give carbonic acid, SO 3 gives sulfuric acid, and P 4 O 10 reacts with water to give phosphoric acid. Metal oxides, on the other hand, are bases. Metal oxides formally contain the O 2 – ion, which reacts with water to give a pair of OH – ions.
Which compound will form an acidic solution when dissolved in water chegg?
calcium nitrate e . all of the above form acidic solutions when dissolved in water. Estimate the pH of 0.175 M NaCN.
Which compound will form an acidic solution when dissolved in water NH4Cl?
Explanation: Ammonium chloride , a water-soluble salt of ammonia, is slightly acidic as a water-based solution. The acidic component of ammonium chloride (Cl-) produces hydrogen (H+) ions when dissolved in water.
When dissolved in water an acidic compound will produce?
When dissolved in water, acidic salts will yield solutions with pH less than 7.0 . This is due either to the presence of a metal cation that acts as a Lewis acid (which will be discussed in a later concept), or, quite commonly, due to a hydrolyzable proton in the cation or the anion.
Which ion must be formed to make a solution acidic?
An acid is a substance which donates hydrogen ions into solution, while a base or alkali is one which takes up hydrogen ions.
Which of the following will produce an acidic solution?
So, our correct choice is (C) Ammonium chloride because it has a strong conjugate acid NH+ which will make solution acidic.
Is NH4Cl acidic when dissolved in water?
Since NH4Cl is made by reacting a weak base (NH3) with a strong acid (HCl), the salt will produce a slightly acidic solution when dissolved in water.
Is NH4Cl weak or strong?
Ammonium chloride is a strong electrolyte because it dissolved fully into ions or 100% ionized in an aqueous solution. 1 Why NH4Cl acts as acidic salt?
Why does NH4Cl produce an acidic solution?
When Ammonium chloride is dissolved in water Ammonium ions and Chloride ions are formed . Ammonium ion is a strong conjugate acid of the weak base of Ammonia whereas chloride ion is a weak conjugate base of the strong Hydrochloric acid. The solution of Ammonium Chloride is therefore acidic.
What are 3 weak acids?
- Formic acid (chemical formula: HCOOH)
- Acetic acid (chemical formula: CH 3 COOH)
- Benzoic acid (chemical formula: C 6 H 5 COOH)
- Oxalic acid (chemical formula: C 2 H 2 O 4 )
- Hydrofluoric acid (chemical formula: HF)
- Nitrous acid (chemical formula: HNO 2 )
What happens to most of the molecules of a strong acid when the acid is mixed with water?
it will completely dissociate in water. ... Most of the molecules of a strong acid are broken apart when it is put in water. What happens to most of the molecules of a strong acid when the acid is mixed with water? A solution of a strong acid has more ions in solution and can conduct electricity better than a weak acid .
Which compound is more soluble in an acidic solution?
Salts that are weakly basic are more soluble in acidic medium than in neutral medium. Salts that are weakly acidic are more soluble in basic medium than in neutral medium.
Is vinegar acidic or basic?
Vinegar is acidic . Vinegar’s pH level varies based upon the type of vinegar it is. White distilled vinegar, the kind best suited for household cleaning, typically has a pH of around 2.5. Vinegar, which means “sour wine” in French, can be made from anything containing sugar, such as fruit.
Is milk an acid or base?
Cow’s milk
Milk — pasteurized, canned, or dry — is an acid-forming food . Its pH level is below neutral at about 6.7 to 6.9. This is because it contains lactic acid. Remember, though, that the exact pH level is less important than whether it’s acid-forming or alkaline-forming.
Is Oh acidic or basic?
OH – is called a hydroxyl ion and it makes things basic . However, in water, there is a balance between hydroniums and hydroxyls so they cancel each others’ charges. Pure water is neither acidic or basic; it is neutral.
