Hydrogen ion concentration of the following acidic solution?

Certainly, let's solve for the hydrogen ion concentration (H+) of the hydrochloric acid solution you described. Here's how we can find it:

1. Calculate the molarity (M) of the HCl solution:
   • Molarity (M) = moles of solute (HCl) / liters of solution (L)

We need to find the moles of HCl first.

1. Convert grams of HCl to moles of HCl:
   • Moles of HCl = grams of HCl / molar mass of HCl

The molar mass of HCl is 36.46 g/mol (1 atom H + 1 atom Cl).

1. Plug the values into the equations:
   • Moles of HCl = 3.45 grams / 36.46 g/mol = 0.0946 mol
   • Molarity (M) of HCl solution = 0.0946 mol / 2.34 L = 0.0404 M

Important Note: Hydrochloric acid (HCl) is a strong acid, meaning it dissociates completely in water. This implies that for every molecule of HCl that dissolves, it releases one H+ ion and one Cl- ion. Therefore, the hydrogen ion concentration (H+) is equal to the molarity of the HCl solution (since each HCl molecule dissociates into one H+ ion).
