What type of reaction is the following reaction NaOH AQ H2SO3 AQ –> Na2SO3 AQ H2O L?
What type of reaction is the following reaction NaOH AQ H2SO3 AQ –> Na2SO3 AQ H2O L?
This is an acid-base reaction (neutralization): H 2SO 3 is an acid, NaOH is a base.
Is H2SO3 aqueous?
It is a colourless gas that has a high solubility in water. In solution, it hydrates to sulphuric acid (H2SO3), which in turn dissociates to form ions of bisulfite (and sulfite (SO2–3)….Is sulphurous acid soluble?

What is the balanced equation for H3PO4 NaOH?
H3PO4 + NaOH = Na3PO4 + H2O | Chemical reaction and equation.
What is the name of H2SO3 AQ?
Sulfurous acid
Is H2SO3 acid or base?
Sulfurous acid, H2SO3, is a weak acid capable of providing two H+ ions (pKa1 = 1.9, pKa2 = 7.0).
Is LiOH an acid or base?
If it is less than 100% ionized in solution, it is a weak base. There are very few strong bases (see Table 12.2 “Strong Acids and Bases”); any base not listed is a weak base. All strong bases are OH – compounds….Learning Objectives.
| Acids | Bases |
|---|---|
| HCl | LiOH |
| HBr | NaOH |
| HI | KOH |
| HNO 3 | RbOH |
Is KBr an acid or base?
Part (a) KBr It is a neutral salt since it is made by the reaction of KOH (a strong base) and HBr (a strong acid).
Is NaCl an acid or base?
Salts That Form Neutral Solutions A solution of NaCl in water has no acidic or basic properties, since neither ion is capable of hydrolyzing.
Is NaCl strong acid?
Compare HCl, NaOH, and NaCl: HCl is a stronger acid than water. NaCl is a weaker base than NaOH. Weaker bases have stronger conjugate acids. NH3 is a weak base, but its conjugate acid, NH4Cl, is a strong acid.
Does NaCl affect pH?
Table salt is called sodium chloride. Neither of them reacts with water, so salt will only change the volume of the water, not its pH. In order for any type of salt to affect the pH (potential of hydrogen), it has to react with water to release or bind the hydrogen atoms from the water.
Is sodium acidic or basic?
Sodium is the most notable of all the alkaline metals from a commercial point of view. To create sodium hydroxide and hydrogen, sodium reacts violently with water, and also with snow and ice. A solution which has a pH of 7 forms a salt derived from the reaction of a strong acid with a strong base.
Is sodium fluoride acidic or basic?
Since sodium fluoride is soluble, the sodium ion is a spectator ion in the neutralization reaction. The fluoride ion is capable of reacting, to a small extent, with water, accepting a proton. The fluoride ion is acting as a weak Brønsted-Lowry base.
Is NaCl a neutral?
Salts that are from strong bases and strong acids do not hydrolyze. The pH will remain neutral at 7. This is why NaCl is a neutral salt.
Is NaOH a salt?
Sodium hydroxide is a molten mixture of inorganic salt that has a melting point of 320°C and able to be used for temperatures up to 800°C. The problem of molten salts is having a behavior that is highly corrosive, and there is difficulty in containing it at high temperatures.
Is NaOH a neutral salt?
Alkali metal and alkaline earth metal hydroxides, such as NaOH, KOH, and Ca(OH)2, are considered strong bases. The con- jugate acid of a strong base is neutral. Neutralization of a strong acid with a weak base gives an acidic salt, while neutralization of a weak acid with a strong base gives a basic salt.
How do you make NaOH at home?
How to Make Sodium Hydroxide
- First you need to get water and put it in a container then mix salt (sodium chloride) in it (make sure the salt isn’t iodized)
- Next put the 2 carbon rods in the water and then apply power.
What type of base is NaOH?
Common examples of strong Arrhenius bases are the hydroxides of alkali metals and alkaline earth metals such as NaOH and Ca(OH)2. Strong bases are capable of deprotonating weak acids; very strong bases can deprotonate very weakly acidic C–H groups in the absence of water.
Why is NaOH a Lewis base?
NaOH is a Brønsted-Lowry base because it accepts H+ ions from acids. NaOH is a Lewis base because the lone pairs on the hydroxide ion can be donated to other compounds.
Is NaOH or ba oh 2 stronger?
Hi friend, Here is your answer: Sodium Hydroxide dissociate completely to give a higher concentration Hydroxyl ions (OH⁻) whereas Barium hydroxide dissociate partially to give a lower concentration of Hydroxyl ions(OH⁻).
Why is NaOH a base?
NaOH is an Arrhenius base because it dissociates in water to give the hydroxide (OH-) and sodium (Na+) ions. An Arrhenius acid is therefore any substance that ionizes when it dissolves in water to give the H+, or hydrogen, ion.
Is NaOH a strong acid or base?
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 |
Is NaOH a salt or a base?
Sodium hydroxide is completely ionic, containing sodium ions and hydroxide ions. The hydroxide ion makes sodium hydroxide a strong base which reacts with acids to form water and the corresponding salts, e.g., with hydrochloric acid, sodium chloride is formed: NaOH( aq) + HCl(aq) → NaCl(aq) + H2O( l)
What is the chemical formula for sodium hydroxide?
NaOH
What happens if you drink sodium hydroxide?
Eating or drinking sodium hydroxide can cause severe burns and immediate vomiting, nausea, diarrhea or chest and stomach pain, as well as swallowing difficulties. Damage to the mouth, throat and stomach is immediate.
Why is sodium hydroxide not stored in glass bottles?
NaOH bottle is not kept open in labs nor is NaOH stored in bottles with glass stoppers. NaOH is hygroscopic. It reacts with CO2 from air to Na2CO3 (also NaHCO3) by the reaction: 2NaOH(aq) + CO2(g) -> Na2CO3(s) + H2O(l). This leads to reduction in base equivalents and hence NaOH is not kept open.
Does NaOH react with plastic?
Plastic is inert to Sodium Hydroxide solution so it can safely stored in plastic containers whereas Sodium Hydroxide reacts with glass Silica that results contamination with Silica.
Can sodium hydroxide dissolve glass?
Sodium hydroxide, aka solid drain cleaner or lye, can easily be stored in glass as a solid, but when molten, it reacts violently with glass and can actually dissolve it away!
Why bases are kept in glass bottles?
Glass bottles are ideal for storing most acids and bases. Ordinary glass is largely inert and does not react chemically with most substances, including aqueous substances like acids and bases. It is also nonporous, which means it will not absorb or contaminate chemicals.
