# What are some common acids found in the home with the amount of pH valve it contains?

Apr 17, 2018

Well, I can come up with a few.

#### Explanation:

Of course, $p H$ values depend on the concentration of ${H}_{3} {O}^{+}$ ions, so the numbers given here are rough estimates of what $p H$ readings you might expect when investigating acids in your home.

If you have soda -(specifically, Cola) It contains phosphoric acid. ${H}_{3} P {O}_{4} \left(a q\right)$, which is why Cola gives a low $p H$ when measured using a probe.

It has a $p H$ of roughly 2-3, because it is a weak acid.

You can also have acetic acid $C {H}_{3} C O O H \left(a q\right)$, in vinegar in your kitchen. Another weak acid with a similar $p H$ range to that of phosphoric acid.

We can also find Citric acid, ${C}_{6} {H}_{8} {O}_{7}$ in lemons. It is another weak acid and also is within the range of acetic acid and phosphoric acid

In a traditional car battery, we can find sulfuric acid ${H}_{2} S {O}_{4} \left(a q\right)$, which has a $p H$ of 1 or , as it is a strong acid.

I guess you can also say that you are also carrying around hydrochloric acid, $H C l \left(a q\right)$ in your stomach- which is another strong acid, giving it a $p H$ value

You can also make Carbonic acid (H_2CO_3(aq)) by carbonating water, which has a $p H$ around 5.6, making it only slightly acidic.

That's all I can come up with, hope it helped!
