3.2
Can range 3-6

Question 9

Is citric acid combustible?

Answer 9

Yes

Question 10

Soda ash
PH

Answer 10

11.6

Question 11

Does soda ash burn?

Answer 11

No
May decompose with heat and may create toxic fumes

Question 13

Step 2
Determine the ________

Answer 13

Strength of the PH

Question 14

Step 3

Answer 14

Create a slurry with the opposing agents

Question 15

Soda ash for?

Answer 15

Acids

Question 16

Citric acid for?

Answer 16

Bases

Question 17

Step 4 after slurry

Answer 17

Apply slurry while re papering with PH to check
Goal is neutral (green on paper)

Question 18

Step 5 after neutral

Answer 18

If any left over slurry
Pour or apply neutralized substance into slurry

Question 19

Caution

Answer 19

This process forms an exothermic reaction. Go slow and wear PPE

Question 20

How does soda ash neutralize acids?

Answer 20

Soda ash (Na₂CO₃) reacts with acids to form water, salt, and carbon dioxide, raising the pH.

Soda ash is a common name for sodium carbonate, which is used in various chemical processes.

Question 21

How does citric acid neutralize bases?

Answer 21

Citric acid donates hydrogen ions (H⁺) to bases, forming water and salt while lowering the pH.

Citric acid is a weak organic acid commonly found in citrus fruits.

Question 22

Why does soda ash produce bubbles during neutralization?

Answer 22

It releases carbon dioxide (CO₂) gas as it reacts with acidic hydrogen ions (H⁺).

The reaction is characterized by effervescence due to the gas release.

Question 23

What makes citric acid effective for alkaline spills?

Answer 23

Its multiple acidic groups bond with hydroxide ions (OH⁻), reducing alkalinity.

Citric acid’s structure allows it to effectively neutralize strong bases.

Question 24

Why does the pH change during neutralization?

Answer 24

Hydrogen ions (H⁺) and hydroxide ions (OH⁻) combine to form water, shifting the pH toward neutral.

This process is fundamental to acid-base chemistry and is essential in various applications.
