Answer:
7
Explanation:
The pH of water is 7.
pH is the convenient scale for expressing the level of acidity or alkalinity of aqueous solutions.
An acidic solution has a pH value less than 7.
As pH decreases, the acidity of solutions increases.
Neutral solutions have a pH of 7.
An alkaline solutions has a pH greater than 7 and the level of alkalinity increases as the pH increases.
Water has a pH of 7 because the concentration of hydrogen and hydroxyl ion is equal.
Answer:
= 2.659 g NaCl
Explanation:
Molarity of a substance is given by the formula;
Molarity = moles/Volume in liters
Thus;
Number of moles = Molarity × volume in liters
= 1.3 M × 0.035 L
= 0.0455 Moles
But, the molar mass of NaCl is 58.44 g/mol
The mass of NaCl is therefore;
= 0.0455 g × 58.44 g/mol
<u>= 2.659 g NaCl</u>
