CHAPTER V
SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS
This chapter reports the summary, conclusions, and recommendations that resulted from this research.
5.1 Summary
The purpose of this research is to know which is more effective in treating stomach aches, a leading antacid or lemongrass tea. For us to determine which of the two is better and safer, we have conducted different experiments. The researchers differentiated the physical properties of the leading antacid and the 4 Lemongrass Tea ‘ samples based on their aroma, texture, and appearance. They also compared the neutralizing capability of the antacid and Lemongrass tea through titration and pH measurement. Lastly, we discovered out of the two subjects which is faster in neutralizing the stomach acid. Through the use of the experimental method of research, we were able to address the research problems. 
In the analysis of physical properties of the antacid and Lemongrass tea, each substance has their own distinctive properties. For the pH level of the antacid, the three trials clearly revealed that it stayed in the 7 pH mark. The 7 pH mark shows that a substance is in a neutral state. The Lemongrass Tea Sample 1, Sample 2, and Sample 3 have a pH below 7 that’s why we did not use it for titration. The Lemongrass Tea Sample 4 reached the 7 pH mark. During the titration of the antacid, the pH result per drop shows that it increases gradually. While for the titration of the Lemongrass tea Sample 4, it decreases fast every drop.
5.2 Conclusion
The researchers concluded based on the comparative analysis shows that the Commercial brand antacid is more effective in treating stomach aches than Lemongrass Tea. 

The commercial brand antacid is more effective as seen in the titration of both substances. At the first drop of HCl in the antacid, it already reached the pH level of 7 and even after the third drop, it still stays at the pH 7 mark while for the Lemongrass tea sample 4, it is also considered as a base because of its average pH but even though it is a base it cannot neutralize an acid like HCl, because the result of titration of Lemongrass Tea sample no.4 shows that the pH level rapidly decreased as HCl drops.
The Lemongrass Tea is dependent on quantity of leaves you will use in a certain amount of water. The more the lemongrass leaves in a specific amount of water, the more it will be effective. That is why in 500-ml distilled water, every 40g of lemongrass leaves will only have a 6.25pH. For every 50g, it will have 6.52pH until it continues to increase.
For the leading antacid, the experiments showed that it is a strong base, which means it has a pH higher than 7. This explains that the leading antacid can neutralize an acidic stomach. Unlike the antacid, the Lemongrass Tea also reached the 7 pH mark but the pH level quickly decreases. 

5.3 Recommendations
Based on the data in this research and also the conclusions drawn, the recommendations are the following:

1.Future researchers can try other brands of antacid.
2.Other researchers can conduct acid-base titration with the correct indicator. We only used titration using HCl as the indicator.
3.Future researchers can also compare other antacids with other herbal medicine which is helpful in stomach aches like using Milk of Magnesia.
4.Future researchers may also broaden and expand the scope. They can focus on other stomach problems other than stomach aches.
