Question

pH का पूरा नाम लिखकर दैनिक जीवन में महत्व बताइए कारण बताइए कि मुंह का pH 5.5 से कम होने पर दांत खराब होने क्यों​

Answer 1

$\huge\star\mathfrak{\underline{\green{Answer}}}\star$

pH = Power of Hydrogen

If it is 7, then it's neutral.

If it is less than 7, then it's acidic in nature.

If it is more than 7, then it's basic in nature.

If pH becomes less than 5.5 inside the mouth, then acids present in the mouth start to demineralize tooth enamel due to which the dentin is exposed which can lead to discomfort.

Answer:

kahīñ akele meñ mil kar jhiñjhoḌ dūñgā use

jahāñ jahāñ se vo TuuTā hai joḌ dūñgā use

mujhe vo chhoḌ gayā ye kamāl hai us kā

irāda maiñ ne kiyā thā ki chhoḌ dūñgā use

badan churā ke vo chaltā hai mujh se shīsha-badan

use ye Dar hai ki maiñ toḌ phoḌ dūñgā use

pasīne bāñTtā phirtā hai har taraf sūraj

kabhī jo haath lagā to nichoḌ dūñgā use

maza chakhā ke hī maanā huuñ maiñ bhī duniyā ko

samajh rahī thī ki aise hī chhoḌ dūñgā use
