Precipitation of cobalt(II) hydroxide from aqueous solution

Chemistry
1 answer:

8 0

Answer:

When an alkali metal hydroxide is added to an aqueous solution of cobalt (II) salt, Cobalt(II) hydroxide precipitates as a solid

Explanation:

When an alkali metal hydroxide is added to an aqueous solution of cobalt (II) salt, Cobalt(II) hydroxide precipitates as a solid . For example, 2 NaOH +Co²⁺  →2Na + Co(OH)₂  

From the water ligands Hydrogen ion attached to the cobalt ion is removed by the hydroxide ions.

From  two of the water molecules , a hydrogen ion has been removed , then the resultant is a complex with no charge i.e. a neutral complex.  

One of the important property of cobalt (II) hydroxide are it is slightly soluble in water and it is insoluble in alkalis.

What mass of solid sodium formate (of MW 68.01) must be added to 150 mL of 0.42 mol/L formic acid (HCOOH) to make a buffer solu-
Sergio [31]

Answer:

We need 4.28 grams of sodium formate

Explanation:

<u>Step 1:</u> Data given

MW of sodium formate = 68.01 g/mol

Volume of 0.42 mol/L formic acid = 150 mL = 0.150 L

pH = 3.74

Ka = 0.00018

<u>Step 2:</u> Calculate [base)

3.74 = -log(0.00018) + log [base]/[acid]

0 = log [base]/[acid]

0 = log [base] / 0.42

10^0 = 1 = [base]/0.42 M

[base] = 0.42 M

<u>Step 3:</u> Calculate moles of sodium formate:

Moles sodium formate = molarity * volume

Moles of sodium formate = 0.42 M * 0.150 L = 0.063 moles

<u>Step 4:</u> Calculate mass of sodium formate:

Mass sodium formate = moles sodium formate * Molar mass sodium formate

Mass sodium formate = 0.063 mol * 68.01 g/mol

Mass sodium formate = 4.28 grams

We need 4.28 grams of sodium formate

Josh decided to mix some vinegar with baking soda. He knew that a reaction occurred because he made careful observations. He not
velikii [3]

Josh was sure that the reaction occurred because of the formation of carbon dioxide (CO₂) which is a gas.

Explanation:

Vinegar contains acetic acid (CH₃-COOH) and baking soda is sodium hydrogen carbonate (NaHCO₃). The reaction between these two compounds will produce sodium acetate (CH₃-COONa), carbon dioxide (CO₂) and water (H₂O).

CH₃-COOH + NaHCO₃ → CH₃-COONa + CO₂ + H₂O

Josh was sure that the reaction occurred because of the formation of carbon dioxide (CO₂) which is a gas.
