Write a balanced equation for the double-replacement precipitation reaction described, using the smallest possible integer coeff
1 answer:
Answer:
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
A double displacement reaction in which on e of the product is formed as a solid is called as precipitation reaction.
The balanced chemical equation is:

Option (B) is the right answer.
Hydronium ion () concentration decreases by the <u>factor of 100</u>, if the pH of a solution increases from 2.0 to 4.0.
The hydrogen ion concentration in water is expressed by pH. Specific to aqueous solutions, pH is the <u>negative logarithm</u> of the hydrogen ion (H+) concentration (mol/L) :
Acidic solutions are those with a pH under 7, and basic solutions are those with a pH over 7. At this temperature, solutions with a pH of 7 are neutral (e.g.<u> pure water</u>). The pH neutrality <u>relies on temperature, falling below 7 if the temperature rises above 25 °C</u>.
<h3>Given: </h3>pH1( initial pH) = 2.0
pH2( initial pH) = 4.0
[H3O+] = initial hydronium concentration
[H3O+]* = final hydronium concentration
<h3>Formula used : </h3><h3>Solution: </h3>
Thus , the concentration of hydronium ion decreases by 100.
