Acidic well water is a result of dissolved carbon dioxide, low calcium carbonate, or run off from mining and industrial areas. Install an acid-neutralizing filter onto your plumbing system to add calcium carbonate and other minerals that can help raise the pH of your water. Adding 1 teaspoon of baking soda per 5 gallons of water is a safe amount for tiny increases if the pH is too low. I firstly calculated the concentration $\ce{HCl}$ in $100\ \mathrm{ml}$ solution = $10^{-3.7}$ = $2.0\times10^{-5}\ \mathrm{mol}$ $\ce{HCl}$ per $100\ \mathrm{ml}$. What are the advantages of running a power tool on 240 V vs 120 V? After adding sodium hydroxide, the amount of substance of hydronium ions is: Assuming the volume of a droplet to be about 60 micro liter, it is much less than a droplet! Unlike neutralizing filters, they do not cause hardness problems in treated water. The solution should be fed directly into the well to protect the well casing and pump from corrosion.

You know your solution is hundred thousand parts per million of this sodium carbonate. Be sure to use borosilicate glass (e.g., Pyrex) and consider immersing the container in a bucket of ice to keep the heat down. Seems like cheap money to me. How much $\ce{NaOH}$ do you need to add to to the $100\ \mathrm{ml}$ solution of $\ce{HCl}$ to get a pH of 4.5? $$1\times{10^{-4.5}} =\frac{0.1\times{10^{-3.7}}-\mathrm{V}_\ce{(NaOH)_\text{added}}\times{10}}{0.1+\mathrm{V}_\ce{(NaOH)_\text{added}}}$$ Most pH water issues can be solved by acid neutralization systems that add minerals to the water to balance pH levels. One exception would be if the water was over saturated with carbon dioxide (sparkling water) the pH would probably not change with NaOH addition until enough of the gas was converted to bicarbonate so that no more gas would leave the solution on its own. If the pH is lower than desired, adjust it using sodium hydroxide solution. We also acknowledge previous National Science Foundation support under grant numbers 1246120, 1525057, and 1413739. The pH of the water will change over time while it is in the tank, which means it needs to be testedevery so often. when you added doses of lye to your system, about how much lye would each dose contain. \[\left[ \ce{H^+} \right] = 10^{-\text{pH}} = 10^{-9.14} = 7.24 \times 10^{-10} \: \text{M}\nonumber \].
