Determining the pH of a 0.667 M NaOH Solution: Determine The Ph In A 0.667 M Naoh Solution
pH is a crucial parameter in chemical solutions, indicating the acidity or alkalinity of a substance. It plays a significant role in various chemical reactions and industrial processes. This article explores the concept of pH, the properties of NaOH, and the steps involved in calculating the pH of a 0.667 M NaOH solution.
Understanding NaOH
NaOH, also known as sodium hydroxide, is a strong base that dissociates completely in water. This dissociation results in the formation of hydroxide ions (OH-) and sodium ions (Na+). The concentration of hydroxide ions in a NaOH solution determines its pH.
Calculating pH from NaOH Concentration
The pH of a NaOH solution can be calculated using the following formula:
pH =
log[OH-]
Where [OH-] is the molar concentration of hydroxide ions in the solution.
Example Calculation
To calculate the pH of a 0.667 M NaOH solution, we can use the formula above:
- NaOH dissociates completely in water, so [OH-] = [NaOH] = 0.667 M
- pH = -log(0.667) = 0.176
Therefore, the pH of a 0.667 M NaOH solution is 0.176.
Applications of NaOH, Determine the ph in a 0.667 m naoh solution
NaOH has numerous applications in various industries, including:
- Paper manufacturing
- Textile processing
- Soap and detergent production
- Water treatment
In each of these applications, the pH of the NaOH solution plays a crucial role in controlling the desired chemical reactions.
