Milk of magnesia is often taken to reduce the discomfort associated with acid stomach or heartburn. the recommended dose is 1 teaspoon, which contains 4.00×102mg of mg(oh)2. part a what volume of an hcl solution with a ph of 1.3 can be neutralized by one dose of milk of magnesia?

Volume of HCl = 0.0688 L

Explanation:

pH is defined as the negative logarithm of the concentration of hydrogen ions.

Thus,  

pH = - log [H⁺]

So, pH = 1.3

Thus, 1.3 = - log [H⁺]

[H⁺] = 0.05012 M

Since, HCl is a strong acid, the concentration of HCl = 0.05012 M

Also,

Moles of :-

Mass =

Also, 1 mg = 0.001 g

So =, Mass =

Molar mass of = 58.32 g/mol

The formula for the calculation of moles is shown below:

Thus,

According to the reaction:-

1 mole of neutralizes 2 moles of HCl

Considering:

So,

Thus,

Appyling values as:-

Volume of HCl = 0.0688 L

answer: they produce more slow than unicellular organisms.
