What are the properties and uses of sodium hydroxide?
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.

Why is NaOH soluble in water?
When sodium hydroxide (NaOH) dissolves in water, it separates into positively – charged sodium ions (cations) and negatively – charged hydroxide ions (anions). These ions move around in the water, free and independent of each other, though cations tend to be surrounded more closely by anions and vice versa.

What happens when NaOH is dissolved in water?
What makes NaOH a strong base?
NaOH is a strong base as it completely dissolves in water to release hydroxide ions (along with sodium ions) which are responsible for the basic nature of an aqueous solution. A Compound that releases OH- ions in an aqueous solution is basic in nature. The pH value of NaOH is around 12 classifying it as a strong base.
Is NaOH an acidic solution?
NaOH is a strong base. It completely dissociates in an aqueous solution and releases a lot of OH– ions.
Is NaOH strong or weak base?
strong bases
Classifying Electrolytes

|---|---|---|
| strong bases | NaOH, KOH, LiOH, Ba(OH)2, and Ca(OH)2 | |
| salts | NaCl, KBr, MgCl2, and many, many more | |
| Weak Electrolytes | ||
| weak acids | HF, HC2H3O2 (acetic acid), H2CO3 (carbonic acid), H3PO4 (phosphoric acid), and many more |
Does NaOH make solutions acidic?
The H+ ions combine with water molecules to form H3O+ so the solution becomes acidic. Now let’s look at lye, a strong base with the chemical formula NaOH (sodium hydroxide). If we add NaOH to water, it dissociates into Na+ and OH-. The sodiums don’t do anything important, but the hydroxyls make the solution more basic.
Why does NaOH dissociate in water?
Why are Metal Hydroxides Bases and Nonmetal Hydroxides Acids? O bond are not shared equally these electrons are drawn toward the more electronegative oxygen atom. NaOH therefore dissociates to give Na+ and OH- ions when it dissolves in water.
What happens to the temperature when NaOH is added to water?
Therefore, the increase in temperature leads to an increase in the process of dissolving $NaOH$ in water. So, the correct answer is Option A . Note: Solubility of a solution is the dissolution of solute particles in a saturated solution. The process of dissolution changes from exothermic to endothermic.
What is a strong NaOH solution?
Explanation: Strong bases are characterized by the fact that they dissociate completely in aqueous solution. In this case, sodium hydroxide, NaOH , is classified as a strong base because it dissociates completely in aqueous solution to form sodium cations, Na+ , and hydroxide anions, OH− .
Is NaOH is strong or weak base?
strong base
Because sodium hydroxide is a strong base that dissociates completely in solution to form hydroxide ions, if the concentration of hydroxide ions in solution is .
Is NaOH acidic basic or neutral?
Why is NaOH strong base?
Sodium hydroxide is a strong base because it dissociates completely in aqueous solution to form sodium cation and hydroxide anion. One formula unit of sodium hydroxide contains one sodium cation and one hydroxide anion, it follows that one mole will contain one mole of sodium cation and one mole of hydroxide anion.
How do you calculate the molarity of NaOH?
How do you find the molarity of NaOH? Method 1: Calculate the number of moles of solute present. mol NaOH. = 15.0g NaOH. x. 1 mol NaOH. 40.0 g NaOH. mol NaOH. Calculate the number of liters of solution present. L soln. = 225 mL. x. 1 L. = Divide the number of moles of solute by the number of liters of solution.
How can the moles of NaOH be calculated?
moles HCL = moles NaOH. We can calculate the number of molesof NaOH at the equivalence point by multiplying its concentration (in terms of molarity or moles/L)by the volume of NaOH added in order to reach the equivalence point: This tells us that there were 0.004398 molesof HCl in our original 0.02500 L solution.
How many moles is 2 pounds of NaOH?
How many grams NaOH in 1 mol? The answer is 39.99711. We assume you are converting between grams NaOH and mole. You can view more details on each measurement unit: molecular weight of NaOH or mol This compound is also known as Sodium Hydroxide. The SI base unit for amount of substance is the mole. 1 grams NaOH is equal to 0.025001806380511 mole.
What is the average molarity of NaOH?
There is no such a thing like average molarity. In industrial production NaOH sold as a solution is mostly 48% ( in water), this is the highest concentration that will stay liquid also on colder days, because you like to transport the max of active product and the least amount of water. you can do the math, 48% is about 12 N or 12 M.
