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

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
