Calculate the ph of a solution that was prepared with 1.46 g of hcl to produce 750 ml of aqueous solution.

pH = 1.27

Explanation:

The reaction is:

HCl(aq)  ⇄  H⁺(aq) + Cl⁻(aq)

We have:

m HCl = 1.46 g

V = 750 ml = 0.750 L

M HCl = 36.458 g/mol  

We know that 1 mol is equal to:

Now, we can find the concentration of HCl:

Finally, the pH of the solution is:

Therefore, the ph of a solution that was prepared with 1.46 g of hcl to produce 750 ml of aqueous solution is 1.27.

I hope it helps you!    

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
