A solution at 25 ∘C has pOH = 10.53. Which of the following statements is or are true? The solution is acidic. The pH of the solution is 14.00 - 10.53. For this solution, [OH−] = 10−10.53 M.

The true statements are:

The solution is acidic

The pH of the solution is 14.00 - 10.53.

Explanation:

The pH of the solution is defined as negative logarithm of hydrogen ion concentration present in the solution .

The pOH of the solution is defined as negative logarithm of hydroxide ion concentration present in the solution .

The pOH of the solution = 10.53

The pH of the solution = ?

Here, the pH of the solution is less than 7 which means that solution acidic.

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."

1. for the first question, we must find the mass of the anhydrous salt, mgso₄. the molar mass for mgso₄·7h₂o is 246.47 g/mol, while that of mgso₄ is 120.37 g/mol.7.834 g mgso₄·7h₂o * 1 mol mgso₄·7h₂o/246.47 g * 1 mol mgso₄/1 mol mgso₄·7h₂o * 20.37 g mgso₄/mol = 0.647 g mgso₄

2. mass of water = mass of sample - mass of anhydrous salemass of water = 7.834 - 0.647 = 7.19 gpercent water in hydrate = 7.19/7.834 * 100 = 91.74%
