Where is caustic soda on the pH scale?
14.0
pH values for bases like sodium hydroxide, ammonia and more.
| Base | Normality | pH |
|---|---|---|
| Sodium bicarbonate (baking soda) | 0.1 N | 8.4 |
| Sodium carbonate (washing soda) | 0.1 N | 11.6 |
| Sodium hydroxide (caustic soda) | N | 14.0 |
| Sodium hydroxide | 0.1 N | 13.0 |
Is caustic soda acidic or basic?
Sodium hydroxide (Na OH), also known as lye or caustic soda, is a caustic metallic base. An alkali, caustic soda is widely used in many industries, mostly as a strong chemical base in the manufacture of pulp and paper, textiles, drinking water, and detergents.
Does caustic soda raise or lower pH?
Caustic soda (sodium hydroxide, or NaOH) is a commonly used water treatment chemical that raises the pH of water by absorbing water and carbon dioxide.
What is the pH of 5% caustic?
1 Answer. The pH is about 12.7.
What is the smallest pH possible?
The range goes from 0 – 14, with 7 being neutral. pHs of less than 7 indicate acidity, whereas a pH of greater than 7 indicates a base.
Is caustic soda strong base?
General information. Sodium hydroxide (caustic soda) is highly soluble in water, and sodium hydroxide solutions are strong bases.
Can you get pH 16?
It describes how many hydrogen ions (protons) are present in a solution: the higher the pH, the lower the hydrogen ion concentration, and vice versa. But the scale does not have fixed limits, so it is indeed possible to have a pH above 14 or below zero.
Does caustic soda dissolve in water?

Can you mix caustic soda and vinegar?
The reaction can be violent and may damage the pipes, could release harmful gases or may not work at all because only a small portion of the blockage is exposed to the vinegar. It’s dangerous to combine caustic soda with any other chemicals in your drain, even hot water, because of the amount of heat released.
What’s the pH of Coca Cola?
2.6 to 2.7
How acidic is Coke? Its pH is reported to be 2.6 to 2.7, mainly due to H3PO4, phosphoric acid. As a fizzy drink, it contains plenty of dissolved carbon dioxide, but this makes very little contribution to the acidity.
Is pH above 14 possible?
But the scale does not have fixed limits, so it is indeed possible to have a pH above 14 or below zero. For example, concentrated hydrochloric acid can have a pH of around -1, while sodium hydroxide solution can have a pH as high as 15.
Does caustic raise pH?
Similar to Lime Slurry, because of the high solubility of Caustic Soda, pH often becomes biologically prohibitive very quickly. This often results in an increased risk of burning (elevated pH) out the microbiology before you can make adjustments.
Which is more dangerous acid or caustic?
is that acid is sour, sharp, or biting to the taste; tart; having the taste of vinegar while caustic is capable of burning, corroding or destroying organic tissue. As nouns the difference between acid and caustic is that acid is a sour substance while caustic is any substance or means which, applied to animal or other organic tissue, burns, corrodes, or destroys it by chemical action; an escharotic.
Why is caustic soda used in drinking water?
Unstable compound. Sodium hypochlorite is a clear,slightly yellowish solution with a characteristic odor.
What is caustic soda and how is it used?
Caustic soda is used in many common household products, for example in the industrial manufacture of paper, fabrics and detergents. In the chemical and pharmaceutical industry it is widely used as a raw material in many synthesis reactions or to adjust the pH of solutions. In mining it is an important substance used in the extraction of many minerals, for example in the extraction of Aluminum
