Question

Will appreciate this to be explained in detail! Thank you.

Write a balanced chemical equation to show the dissociation of each salt and write the names of the parent acid/base pairs for each of the following salts: lithium carbonate (Li2CO3) strontium oxalate (SrC7O4) ammonium acetate (NR4C2H3O2) 2. As a first step, write the dissociation reaction that occurs when a salt is first added to water. Second, write the hydrolysis reactions that occur when each of the following salts is added to water (treat the cation and anion hydrolysis (or not) as separate reactions) and predict whether the resulting solutions will be acidic, basic, or neutral. If there is no reaction write no reaction KBr Al(NO3)3 Na2SO3 3. Water in contact with the atmosphere is always slightly acidic, rather than neutral. Explain why. Write a balanced chemical equation. 4. Consider the indicator tests for the hypothetical salt that was shown during the CH229 lab lecture. What indicator was used? Estimate the pH of the solution.

Explanation / Answer

1 a) Balanced equation is

Li2CO3 --> 2Li+ + CO3-2

This is a salt of strong base Lithium hydroxide (LiOH) and weak acid carbonic acid (H2CO3)

b) Strontium oxalta

SrC2O4 --> Sr+2 + C2O4-2

This is salt of Sr(OH)2 and oxalic acid (H2C2O4)

c) Ammonium acetate

NH4C2H3O2 --> NH4+ + C2H3O2-

Salt of ammoium hydroxide (NH4OH) base and acetic acid (CH3COOH)
