Answer 1

when NAOH is added it's ph will be more than 7 if with hcl then ph will be less than 7

Answer 2

As we know that NaCl is basic in nature. And the ph value of base is more than 7 . So, the ph value of NaCl will be MORE THAN 7.......

Similarly , Dilute Hcl is acidic in nature . And the ph value of acid is less than 7 . So, the ph value of Hcl will be LESS THAN 7........
