What else can I help you with?
When you lower the pH of a solution containing aqueous sodium benzoate a precipitate eventually forms What will happen if you then raise the pH after the reaction by adding aqueous NaOH?
When you raise the pH by adding aqueous NaOH after a precipitate forms in a solution of aqueous sodium benzoate due to a pH decrease, the precipitate likely dissolves. This is because sodium benzoate is the conjugate base of benzoic acid, so at higher pH levels, it remains in solution. The sodium benzoate will revert back to being fully soluble in its aqueous form.
Aqueous solutions of Barium Nitrate and Sodium Hydroxide are combined Does a precipitate form?
Yes, a white precipitate of barium hydroxide would form due to the reaction between barium nitrate and sodium hydroxide forming insoluble barium hydroxide. This can be observed as a cloudiness or white solid settling at the bottom of the solution.
What happens in the reaction between sodium hydroxide and magnesium sulphate?
When sodium hydroxide reacts with magnesium sulfate, a double displacement reaction occurs where the sodium ions from sodium hydroxide switch places with the magnesium ions from magnesium sulfate to form sodium sulfate and magnesium hydroxide. The products of this reaction are aqueous sodium sulfate and a white precipitate of magnesium hydroxide.
What happens when aqueous ammonia is added to lime water?
When aqueous ammonia is added to lime water, a white precipitate of calcium hydroxide is formed as the ammonia reacts with the calcium hydroxide present in the lime water. This reaction can be represented as: Ca(OH)2 + 2NH3 → Ca(NH2)2 + 2H2O.
What does iron sulphate solution and sodium hydroxide solution react to make and are the products aqueous?
Fe SO3 (aq) + 2 NaOH (aq) == Fe(OH)2 (s) +Na2So3
What will be the observation when you will add aqueous sodium hydroxide is added to aqueous iron 3 sulphate?
A brown precipitate of iron(III) hydroxide will form, along with the sodium sulfate remaining in solution. The iron(III) hydroxide precipitate will settle at the bottom of the container.
A precipitate will be formed when an aqueous carbonic acid solution is added to an aqueous solution of?
Calcium chloride. When carbonic acid is added to a solution containing calcium chloride, a white precipitate of calcium carbonate is formed due to the reaction of calcium ions with carbonate ions from carbonic acid.
What is the observation of few drops of aqueous sodium hydroxide added to aqueous beryllium chloride?
When aqueous sodium hydroxide is added to aqueous beryllium chloride, a white precipitate of beryllium hydroxide (Be(OH)2) is formed. Beryllium hydroxide is insoluble in water, hence it appears as a white solid.

When aqueous solutions of iron(III) sulfate (Fe2(SO4)3) and sodium hydroxide were mixed a precipitate formed. What is the precipitate?
When aqueous solutions of iron(III) sulfate (Fe2(SO4)3) and sodium hydroxide (NaOH) are mixed, a precipitate of iron(III) hydroxide (Fe(OH)3) forms. This occurs due to the reaction between the iron(III) ions and hydroxide ions, leading to the formation of the insoluble hydroxide. The balanced chemical equation for the reaction is: Fe2(SO4)3 + 6 NaOH → 2 Fe(OH)3 (s) + 3 Na2SO4.
What happens in the reactions of aqueous bromide ions with aqueous silver nitrate following by the addition of concentrated aqueous ammonia?
When aqueous bromide ions react with aqueous silver nitrate, a white precipitate of silver bromide is formed. Upon addition of concentrated aqueous ammonia, the precipitate dissolves due to the formation of a complex ion called the diamminesilver(I) ion, [Ag(NH3)2]+. This reaction forms a colorless solution.

What does iron sulphate solution and sodium hydroxide solution react to make and are the products aqueous?
Fe SO3 (aq) + 2 NaOH (aq) == Fe(OH)2 (s) +Na2So3
Why is aqueous ammonia also called ammonia hydroxide?
Aqueous ammonia is sometimes called ammonium hydroxide because ammonia (NH3) reacts with water to a small degree to produce ammonium hydroxide (NH4OH).NH3 + H2O NH4OHBecause ammonia is a weak base only small amounts of ammonium hydroxide are actually formed and an equilibrium is established.
What are acids and bases according to Arrhenius?
According to Arrhenius, acids are substances that release hydrogen ions (H+) in aqueous solutions, while bases are substances that release hydroxide ions (OH-) in aqueous solutions. Acids increase the concentration of H+ ions, whereas bases increase the concentration of OH- ions.
