What is the pH of lye?
When the pH of a substance is above 7, it is a basic substance. When the pH of a substance is below 7, it is an acid substance. The further the pH lies above or below 7, the more basic or acid a solution is….Acids and bases.
| pH | product |

| 14 | sodium hydroxide |
| 13 | lye |
| 12.4 | lyme |
| 11 | ammonia |
What is the likely pH of sodium hydroxide?

What is sodium hydroxide lye used for?
Other common names include caustic soda and lye. Sodium hydroxide is used to manufacture soaps, rayon, paper, explosives, dyestuffs, and petroleum products. It is also used in processing cotton fabric, laundering and bleaching, metal cleaning and processing, oxide coating, electroplating, and electrolytic extracting.
How does hydroxide affect pH?
pH. The hydroxide ions from dissolved sodium hydroxide perturb this balance; as the additional hydroxides accept protons from hydronium ions, they decrease the hydrogen ion concentration, thereby increasing the pH. Adding more sodium hydroxide will increase the pH of the water or make it more basic.
How does pH adjust with NaOH?
If the pH is higher than desired, adjust it using a hydrochloric acid solution. If the pH is lower than desired, adjust it using sodium hydroxide solution. Fill a plastic pipette with the correct solution, add a few drops to the solution in the beaker and wait at least 20 seconds before reading the pH on the meter.
Is sodium hydroxide acidic?
Sodium hydroxide (NaOH) or lye is considered to be alkaline. It is considered a strong base because it can dissociate from the hydrogen ion into a…
Why is lye used in soap?
Lye, which has a scientific name of sodium hydroxide, reacts when it is properly mixed; the process of mixing and causing this reaction is called saponification. The process typically involves mixing lye with oils or butters, which contribute scents and other natural properties, such as vitamins and minerals, to soap.
