Complete the following table for a selection of foods:
Food | [H3O+] | [OH−] | pH | Acidic,basic,orneutral? |
Strawberries | 3.90 | |||
Soy milk | neutral | |||
Milk | 6.6×10−7M |
Part A: Calculate the [H3O+] of strawberries with pH=3.90 .Express the molarity to two significant figures.
Part B: Calculate the [OH−] of strawberries with pH=3.90 . Express the molarity to two significant figures.
Part C: Calculate the [H3O+] of soy milk. Express the molarity to two significant figures.
Part D: Calculate the [OH−] of milk with [H3O+] = 6.6×10−7M . Express the molarity to two significant figures.
Part E: Calculate the pH of milk with [H3O+] = 6.6×10−7M . Express the pH to two decimal places.
