The following are neutral salts: NANO3, BaBr2 AND Ba[OH]2. 
Neutral salts are those salts that are formed when a strong base react with a strong acid. In those neutralization reactions, the base completely neutralize the acid to form a neutral salts.

The following are neutral salts: NANO3, BaBr2, AND Ba[OH]2.

<h2>Further Explanation </h2>

Salt is an ionic compound consisting of positive ions (cations) and negative ions (anions), thus forming neutral (without charged) compounds. The most common and widely used salt is NaCl salt, a white crystalline solid.

Salt is formed as a result of acid and base reactions. Salt that is hydrolyzed and forms hydroxide ions when dissolved in water is called base salt. Salt that is hydrolyzed and forms hydronium ions in water is called an acid salt. Neutral salt is salt that is neither acid salt nor basic salt.

Salts derived from strong acids and strong bases are usually stable and odorless, while salts formed from weak acids or weak bases have more odor.

Salt hydrolysis only occurs IF one or both of the components of the salt are weak acids and or weak bases.

The salt solution is a solution obtained from the results of acid and base reactions.

The properties of salt, as follows:

  • Able to conduct electric current,
  • does not change the color of litmus red or blue.
  • If it is formed from strong acids and weak bases, then the salt will be acidic. and conversely, if formed from weak acids and strong bases, the salt will be alkaline.
  • When formed from strong acids and strong bases, the salt will be neutral, for example, table salt (NaCl).
  • Has a pH of 7

CaO + H2O -&gt; Ca(OH)2
yawa3891 [41]

The % yield of Ca(OH)₂ : 62.98%

<h3>Further eplanation </h3>

Percent yield is the compare of the amount of product obtained from a reaction with the amount you calculated

General formula:

Percent yield = (Actual yield / theoretical yield )x 100%

An actual yield is the amount of product actually produced by the reaction. A theoretical yield is the amount of product that you calculate from the reaction equation according to the product and reactant coefficients

Reaction

CaO + H₂O ⇒ Ca(OH)₂

mass CaO= 4.2 g

mol CaO(MW=56,0774 g/mol) :

\tt mol=\dfrac{mass}{MW}\\\\mol=\dfrac{4.2}{56,0774 g/mol}\\\\mol=0.075

mol Ca(OH)₂ based on mol CaO

mol ratio CaO : Ca(OH)₂,= 1 : 1, so mol Ca(OH)₂ = 0.075

mass Ca(OH)₂(MW=74,093 g/mol) ⇒ theoretical

\tt mass=mol\times MW\\\\mass=0.075\times 74,093 g/mol\\\\mass=5.557~g

% yield :

\tt =\dfrac{actual}{theoretical}\times 100\%\\\\=\dfrac{3.5}{5.557}\times 100\%\\\\=62.98\%
