a solution has Ph is 8 if it is diluated with an equal volume of water, What will happen to its Ph? explain it ChatGPT said: ChatGPT When a solution with a pH of 8 is diluted with an equal volume of water, its pH will increase slightly but not significantly. Here's why: Nature of the Solution: A pH of 8 indicates a weakly basic solution, meaning the concentration of hydroxide ions [OH − ] [OH − ] is slightly higher than that of hydrogen ions [H + ] [H + ]. Dilution Effect: When you dilute the solution by mixing it with an equal volume of water: The concentration of all ions, including [OH − ] [OH − ] and [H + ] [H + ], is halved. Since the [OH − ] [OH − ] is reduced, the equilibrium of water ( H 2 O ↔ H + + OH − H 2 O↔H + +OH − ) slightly shifts to generate more [OH − ] [OH − ]. pH Change: pH is calculated using pH = − log 10 ( [H + ] ) pH=−log 10 ([H + ]). After dilution, the [H + ] [H + ] will slightly decrease because the weakly basic solution's properties dominate, leading to a small increase in pH. However, the change is minor because the pH scale is logarithmic, and dilution by a factor of 2 only slightly changes the ion concentrations. Conclusion: The pH of the solution will increase slightly above 8 but remain close to it. increase slightly above 8

When a solution with a pH of 8 is diluted with an equal volume of water, its pH will increase slightly but not significantly. Here's why:
Nature of the Solution: A pH of 8 indicates a weakly basic solution, meaning the concentration of hydroxide ions
[OH

[OH

[H

[H

Dilution Effect: When you dilute the solution by mixing it with an equal volume of water:
The concentration of all ions, including
[OH

[OH

[H

[H

Since the

pH Change:
pH is calculated using

pH=−log

After dilution, the

[H

However, the change is minor because the pH scale is logarithmic, and dilution by a factor of 2 only slightly changes the ion concentrations.
Conclusion:
The pH of the solution will increase slightly above 8 but remain close to it.
increase slightly above 8
Got it.....means equal volume of water is neglegible...@@78150ritesh
Got nhi hai sir
अगर किसी विलयन का pH 8 है और उसे पानी की समान मात्रा से पतला किया जाए, तो इसका pH लगभग 7 के बराबर होगा.
Sir k answer bhi mere hisab se sahi hai agar kam Hua to 7 Se To fir below acid ho jaega...!
Bhai 10 guna ke hisab ph me changes aata hai jab same quantity me water milaya jata hai isaliye kam hokar 7 hi hoga@@AkashMishra-ep8xf
