Answer:
[OH-] = 6.17 *10^-10
Explanation:
Step 1: Data given
pOH = 9.21
Step 2: Calculate [OH-]
pOH = -log [OH-] = 9.21
[OH-] = 10^-9.21
[OH-] = 6.17 *10^-10
Step 3: Check if it's correct
pOH + pH = 14
[H+]*[OH-] = 10^-14
pH = 14 - 9.21 = 4.79
[H+] = 10^-4.79
[H+] = 1.62 *10^-5
6.17 * 10^-10 * 1.62 * 10^-5 = 1* 10^-14

Answer: When baking soda and vinegar are combined, a new substance is produced. The carbon dioxide gas soon foams up in the mixture. Carbon dioxide, water, and sodium acetate are generated when sodium bicarbonate and acetic acid react.As Kobe adds additional baking soda and vinegar, the reaction will also become stronger.
