Antacid tablets have a pH greater than 7.
They neutralize the acid in the stomach. Antacid tablets are usually hydroxides of aluminum or magnesium or the carbonates of sodium or calcium.
Too much intake of antacids can lead to health problems. Aluminium may tie up phosphate in the body and causes constipation as does calcium whereas the magnesium salts can lead to diarrhea. Antacids can lead to kidney problems and / or hypertension.
Since, an antacid tablet neutralizes the acid, hence it must be a base.
Now, the pH of the tablet depends on its strength and varies.
But since it is basic, the pH must lie somewhere between 10-14
Strong acids would be located at the lower end of the pH scale, around 1 or 2. The lower the pH of a substance, the more acidic it is.
The pH scale is 10-14
The acic side is the left side of the scale
A strong acid has a pH of 0-2
the pH scale goes from 0 to 14. 0-3 is strong acid (eg. hydrochloric acid), 4-6 is not strong acid. 7 is neutral, eg. water. 8-10 is not strong alkali (base) and 11-14 is strong alkali (eg.sodium hydroxide)
we would find on the pH scale. if the colour is red orange or dark yellow this would be a strong acid. if the colour is yellow or light yellow or normal yellow this would be a weak acid. i hope this helps you thank you
Lowest pH, strong acids, then weak acids, then salts of strong acids and strong bases, then salts of weak acids and strong bases, then weak bases, then strong bases. All very confusing!

Acids have a pH under 7, alkalis have a pH bigger than 7.
The pH scale is between 0 and 14 but a pH under 0 is possible for some strong acids.

No. Alkali's and acids are an separate ends of the pH scale, the pH of acids being 1, 2, 3, 4 and 5 (strong to weak) and the pH of alkali's being 11, 12, 13, 14 and 15 (weak to strong). Examples of acids are hydrochloric acid (strong) and vinegar (weak). Toothpaste is an example of a weak alkali.
strong acid
The PH scale is the measurement of acids and bases. 8 and up are bases. 6 and lower are acids. 7 is neutral.
