FAQS on 0.5 n naoh solution

Q: How do I prepare 0.5 N NaOH solution from 40% NaOH solution?

A: First, calculate the density of 40% NaOH (approximately 1.43 g/mL). Dilute 6.25 mL of 40% NaOH with distilled water to 1 L. This yields a 0.5 N solution due to its molarity and valence.

Q: What is the difference between 0.5 N NaOH and 5 M NaOH solutions?

A: 0.5 N NaOH equals 0.5 M NaOH since NaOH has a valence of 1. A 5 M solution is 10 times more concentrated. Normality (N) and molarity (M) are identical for NaOH.

Q: Can I use 4M NaOH to make a 0.5 N NaOH solution?

A: Yes, dilute 125 mL of 4M NaOH to 1 L with water. Since 4M NaOH is equivalent to 4N, dilution achieves 0.5 N. Ensure proper mixing and calibration.

Q: How to convert 40% NaOH solution to molarity or normality?

A: Use the density (≈1.43 g/mL) to calculate molarity: (400g NaOH / 40 g/mol) / (1000g / 1430 g/L) ≈ 14.3 M. Normality equals molarity (14.3 N) for NaOH.
