Question

The pH values of 4 solutions a b c and d are 5,12 ,8 and 9 respectively arrange them in increasing order of the hydroxyl Ion concentration , which of them has strong acidic property? Explain what happens if your mouth contains the pH of solution a

Answer 1

pH of solution A , B , C and D are 5 , 12 , 8 and 9 respectively.

A base has more Hydroxide ( Hydroxyl ) ion concentration than an acid.

Therefore, Arrangement of these solutions with increasing hydroxyl ion concentration will be:

Solution A < Solution C < Solution D < Solution B

Solution A will have more acidic property because It has less hydroxyl ion concentration and a bit higher hydronium ion concentration. ( Its pH is also less than 7 and least from the following solutions, which makes it more acidic )

If we put Solution A in our mouth that means we are changing the pH of our mouth to 5 that means Our mouth will be acidic. And this acidic environment will soften the enamel and dentine of our teeth and this leads to Tooth Decay ( cavity in teeth )

Answer 2

Answer:

• A = 5

• B = 8

• C = 9

• D = 12

Solution A has strong acidic property .

If our mouth contains ph of solution of A our tooth starts decaying. Producing gum problems.
