When ammonium perchlorate, NH4ClO4, is dissolved in water, will it give an acidic, basic, or neutral solution? Ammonium perchlor
ZanzabumX [31]

<u>Answer:</u> The solution will be an acidic solution when ammonium perchlorate is dissolved in water.

<u>Explanation:</u>

Salts are formed when an acid reacts with a base during a neutralization reaction.

  • When a strong acid and a weak base reacts, it leads to the formation of acidic salt.
  • When a strong base and weak acid reacts, it leads to the formation of basic salt.
  • When a strong acid and strong base or weak acid and weak base reacts, it leads to the formation of neutral salts.

Ammonium perchlorate is formed by the combination of perchloric acid (HClO_4) which is a strong acid and ammonium hydroxide (NH_4OH) which is a weak base.

So, the salt formed which is ammonium perchlorate is an acidic salt and its dissolution in water will make the solution acidic in nature.

NH_4ClO_4+H_2O\rightarrow HClO_4+NH_4OH

Hence, the solution will be an acidic solution when ammonium perchlorate is dissolved in water.

a solution is to be prepared with a sodium ion concentration of 0.555 mol/l. what mass of sodium sulfate (g) is needed to prepar
seraphim [82]

Mass of sodium sulfate (g) is needed to prepare 2.00 liters of such a solution is  78.122.

Sodium Sulfate =N a_2 \mathrm{So}_4$.

$[\mathrm{Na}+]=0.555 \mathrm{mo} / / \mathrm{L}$

$\mathrm{mol} \mathrm{Nat}=0.555 \times2 =1.11 \mathrm{~mol}$

mol \mathrm{Nu}_2 \mathrm{Su}_4=\frac{1.11}{2}=0.55 \mathrm{~mol}$.

mol $\mathrm{Na}_2 \mathrm{So}_4=m_0 \times m \omega$ = 0.55 *142.04=78.122.

Drying organic liquids uses sodium sulphate. in powdered household laundry detergents as a filler. to eliminate minute air bubbles from molten glass as a fining agent. The decahydrate form of Glauber's salt is used as a laxative to eliminate medicines like acetaminophen from the body. The inorganic substance sodium sulfate and numerous related hydrates have the formula Na2SO4. White solids in all of their forms, they are very soluble in water. The decahydrate is a significant commodity chemical product, with a 6 million tonne yearly production.
