Find the pH of HCl with a concentration of 0.00006M Round to the nearest whole number
1 answer:
Answer:
4.22
Explanation:
pH stands for potential hydrogen. The letter “p” denotes potential and the letter “H” denotes hydrogen.
pH helps to find the acidity or alkalinity of an aqueous solution.
The number of hydrogen ions (protons) present in a solution is determined by the pH scale.
A pH greater than 7 makes the water more alkaline and a pH less than 7 makes the water more acidic.

Explanation:
Whenever a similar problem is involved, we need to write the chemical reaction representing the net change, as well as due to the fact that we need to know the stoichiometry involved.
Sodium chloride reacts with silver nitrate in a double displacement reaction to produce a cation exchange, that is, we produce silver chloride and sodium nitrate given by the following balanced chemical equation:
According to the balanced chemical equation, the molar stoichiometry of silver nitrate to sodium chloride is 1 : 1.
Let's find moles of each substance to determine the limiting reactant. To do this, divide mass of each component by its molar mass:
Since the stoichiometry of this reaction is 1 : 1, we can compare the moles directly. Notice that the number of moles of NaCl is lower than the number of moles of silver nitrate. This means NaCl is the limiting reactant.
According to the balanced chemical equation, 1 mole of NaCl produces 1 mole of AgCl, so the amount of AgCl would be:
In order to convert this into mass, let's multiply by the molar mass of AgCl:
