Answer:
Limewater is nothing but calcium hydroxide Ca(OH)_2. So it is basic
Vinegar is acidic in nature
Toothpaste is again, basic in nature as neutralises the acid secreted by the bacteria in our teeth (prevention of degradation of the tooth)
Shampoo is a weak acid
Curd contains lactic acid, so it is acidic in nature
Stomach juices contain hydrochloric acids, so again, acidic in nature
Baking soda is a mixture of a strong base and weak acid. So basic in nature
Soda water is carbonated. Carbon-dioxide has a pH less than 7. So soda water is therefore acidic in nature.
