Reviewer 2 Report
The paper on " Investigation on surface tension properties of binary solution (acetone-water) based on hydrogen bonding by Raman spectroscopic " , is an important contribution. However, the English has to be improved. Eg., inclusion of either " Raman spectroscopy " or "Raman spectroscopic methods " in the title would be more suitable. There are a lot of places where English has to be improved.
Some repetition of texts are present, eg., lines 128-131.
Figure 2,3 or 6 captions contain "acetonitrile ". But this study is based on water and acetone mixtures. Please correct it.
However, in the discussion section, lines 164-166 , the authors have argued that the combination of acetone and water reduces the polarity of water and thus OH bond gets elongated and there is a blue shift in Raman spectra. But this is contradictory to Figure 5. As I understood, Figure 5 shows that with increase in acetone content , ie., with increase in molar ratio in the x axis, the wave number of OH stretch increases, so OH bond length should decrease. Please clarify this part.
Lines 185-186; " The Raman shift of the OH bond is about 8 times of C=O..". As C=O is a double bond , whereas O-H is a single bond, it is generally easier to change the OH bond length compared to C=O bond length. So, to compare the change in wave number , I think a relative percentage change , and also correlation of change in OH /C=O bond length with corresponding change in wave number in Raman spectra , would be of importance.

√Dear editor and reviewers,
We have made changes to the repeated expressions in the text.

√Dear editor and reviewers,
We have corrected the errors in the figure2, 3, 6 captions.
Point 4: However, in the discussion section, lines 164-166, the authors have argued that the combination of acetone and water reduces the polarity of water and thus OH bond gets elongated and there is a blue shift in Raman spectra.

Please clarify this part.
√Dear editor and reviewers,
Previous analysis is incorrect, and there is a red shift in Raman spectra about OH bond. The specific analysis modified in manuscript.
Line 161-168.
Point 5: Lines 185-186; " The Raman shift of the OH bond is about 8 times of C=O…". As C=O is a double bond, whereas O-H is a single bond, it is generally easier to change the OH bond length compared to C=O bond length. So, to compare the change in wave number, I think a relative percentage change, and also correlation of change in OH /C=O bond length with corresponding change in wave number in Raman spectra, would be of importance.
√Dear editor and reviewers,
The change in the length of OH bond and C=O bond is indeed related to the change in wave number and are worthy of further study. We quoted reference to discuss the change in the length of C=O bond. Specific analysis can be found in the text.
Line 190-197.
We are look forward to hearing from you.
