write a balanced net ionic equation for the following reaction: BaCl2(aq) + H2SO4 (aq) -- BaSO4(s) + HCl (aq)
Fudgin [204]

The  balanced net  equation  for

BaCl2 (aq)  + H2SO4(aq) → BaSO4(s)  + HCl  (aq)  is

 Ba^2+(aq)  +SO4^2- → BaSO4 (s)

 <u><em>Explanation</em></u>

Ionic equation  is a chemical  equation in which  electrolytes  in aqueous  solution are written as dissociated ions.

<u>ionic equation is written using the below steps</u>

Step 1:  <em>write a balanced   molecular equation</em>

 BaCl2 (aq) +H2SO4 (aq)→ BaSO4(s)  +2HCl (aq)

Step 2:   <em>Break all soluble  electrolytes  in to ions</em>

=  Ba^2+ (aq) + 2Cl^-(aq)  + 2H^+(aq) + SO4^2-(aq)→ BaSO4(s)   + 2H^+(aq)  +2Cl^- (aq)


step 3:  <em>cancel the spectator  ions  in both side of equation ( ions which  do not take place in the reaction)</em>

<em> </em><em>    =</em> 2Cl^-  and  2H^+  ions

Step 4: <em>write the final net equation</em>

<em> Ba^2+(aq)  + SO4^2-(aq)→  BaSO4(s</em><em>)</em>

Use Appendix C to choose the solution with the lower pH:0.1MBeCl₂ or 0.1MCaCl₂
musickatia [10]

A lower pH means that there are extra hydrogen ions in the liquid, whereas a higher pH indicates fewer hydrogen ions in the liquid. In simple terms, pH is a scale from 1 to 14 that measures the acidity or alkalinity of a liquid.

The hydrated ion undergoes hydrolysis in solution producing `H3O+ . This occurs because the Be-O bond is very strong and so in the hydrated ion and it  weakens the 0-H bond. Hence, there is a strong tendency to lose protons. For this particular reason, the aqueous solution of `BeCl_2` is acidic in nature.

<h3>Will baking soda decrease pH?</h3>

Baking soda, also regarded as sodium bicarbonate is naturally alkaline, with a pH of 8 When you add baking soda to your pool water, you will increase both the pH and the alkalinity, improving balance and clarity. Many industrial pool merchandise for elevating alkalinity utilize baking soda as their most important active ingredient.
