Answer 1

`\textsf {baking soda, oven cleaner, and human blood}`

Step-by-step explanation:

`\textsf {On the pH scale, basic substances have a pH greater than 7.}`

`\textsf{The pH values of all basic substances are listed below :}`

`\implies \textsf {Baking soda = 9}\\\implies \textsf {Oven cleaner = 11 to 13}\\\implies \textsf {Human blood = 7.35 to 7.45}`
