Separate the following into substances having pH values above and below 7. How do these influence litmus paper?(i) Lemon juice (ii) Solution of washing soda (iii) Toothpaste (iv) Vinegar (v) Stomach juices
pH Value above 7 :
(ii) Solution of washing soda
(iii) Toothpaste
pH value below 7:
(i) Lemon juice
(iv) Vinegar
(v) Stomach juices
The substances having a pH value above 7 turns red litmus paper to blue due to their basic nature.
The substance having a pH value less than 7 will turn blue litmus paper into red due to their acidic nature.
