Answer: Option (d) is the correct answer.

Explanation:

According to Bronsted and Lowry, acids are the species which dissociate in water to give hydrogen ions.

Whereas bases are the species which dissociate into water to give hydroxide ions.

Also, like dissolves like. So, when an acid is polar in nature and dissolved in water then it will completely dissociate into ions.

As a result, it will tend to donate hydrogen ions into the solution.

For example, HCl \rightarrow H^{+} + Cl^{-}

Thus, we can conclude that an acid is a polar substance that dissolves in water and donates hydrogen ions to the solution.

Answer: d. donates hydrogen ions to the solution

Explanation:

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions (OH^-) when dissolved in water and an acid is defined as a substance which donates hydrogen ions (H^+) in water.

HX\rightarrow H^++X^-

BOH\rightarrow B^++OH^-

According to the Bronsted Lowry conjugate acid-base theory, an acid is defined as a substance which donates protons and a base is defined as a substance which accepts protons.

Thus an acid is a polar substance that dissolves in water and donates hydrogen ions to the solution.

Question 3 (Molarity)
antiseptic1488 [7]

Answer:

The molarity of the solution is 1,03 M.

Explanation:

Molarity is a concentration measure that expresses the moles of solute (in this case HBR) in 1 liter of solution (1000ml). First we calculate the mass of 1 mol of HBr, to calculate the moles that are in 50 g of said compound:

Weight 1 mol HBr= Weight H + Weight Br= 1,01g + 79,90g= 80, 91 g/mol

80,91 g ----1 mol HBr

50,0 g------x= (50,0 g x1 mol HBr)/80,91 g= 0,62 mol HBr

600 ml solution-----0,62 mol HBr

1000ml solution------x= (1000ml solution x 0,62 mol HBr)/600 ml solution

<em>x=1,03 moles HBr ---> The solution is 1,03M</em>
