Answer : The number of sodium ions is equal to the number of formula units of salt.
Explanation : In the given reaction of NaCl the statement which describes it the best is that the number of sodium ions is found to be same along with the formula units in the product side.
+ ----> NaCl.
Its clear from the equation that one mole of Na and one mole of Cl combines together to give the product, which is one mole of NaCl. The number of ions on both the sides are equal.
Ionicly
They do not share electrons. All of the electrons get attracted the the group 7 element and they stick together electrostaticly.
Answer:
<h2>pH = 4.44 </h2>
Explanation:
The pH of a substance can be found by using the formula
where [ H+ ] is the hydrogen ion concentration of the solution
From the question
[ H + ] = 3.60 × 10^-5 M
So the pH is
We have the final answer as
<h3>pH = 4.44 </h3>
