2. Why some common laboratory apparatus like beakers, evaporating dish, graduated cylinder and others have a small spout or "beak"?
Beakers, evaporating dish, graduated cylinder and others have a small spout (or "beak") to aid pouring
Beakers are available in a wide range of sizes, from one millilitre up to several litres.
3. what is the use of evaporating dish
Evaporating dishes are used to evaporate excess solvents - most commonly water - to produce aconcentrated solution or a solid precipitate of the dissolved substance. Most are made of porcelain or borosilicate glass.
4. evaporating dish meaningPlease in your own opinion.

17. Calculations (Show your solutionMass of NaHCOs(Mass of evaporating dish +NaHCO3)- (Mass of evaporating dish)gMass of NaCl (actual yield(Mass of evaporating dish +NaCl)- (Mass of evaporating dish)Mass of NaCl (theoretical yield)_NaHCO3 (s) + HCl(aq)NaCl(aq) + H₂O(l) +_CO2 (g)
I can certainly help you with those calculations!
To find the mass of NaHCO3:
Mass of NaHCO3 = (Mass of evaporating dish + NaHCO3) - (Mass of evaporating dish)
To find the mass of NaCl (actual yield):
Mass of NaCl (actual yield) = (Mass of evaporating dish + NaCl) - (Mass of evaporating dish)
To find the theoretical yield of NaCl, we need to balance the chemical equation and use stoichiometry. The balanced equation is:
NaHCO3 (s) + HCl (aq) → NaCl (aq) + CO2 (g) + H2O (l)
From the balanced equation, we can see that the molar ratio of NaHCO3 to NaCl is 1:1. This means that for every one mole of NaHCO3, we should get one mole of NaCl. We can use this information to find the theoretical yield of NaCl:
Theoretical yield of NaCl = (mass of NaHCO3 / molar mass of NaHCO3) x (molar mass of NaCl / 1 mol NaHCO3)
Once you have the theoretical yield of NaCl, you can calculate the percent yield by dividing the actual yield by the theoretical yield and multiplying by 100:
Percent yield = (actual yield / theoretical yield) x 100
I hope this helps! Let me know if you have any further questions.

20. Put a little of the HCI and sodium carbonate solution in an evaporating dish. With the use of crucible tongs, hold the dish over a burner flame. Evaporate the solution. Then taste the residue when it is no longer hot. What is the taste?
Answer:Methods of acid-base titration based on a sample dissolution exceeding normal acid, followed by back titration with a standard base is characterised in this experiment. Using bromophenol blue as an indicator, hydrochloric acid solutions were standardised against pure sodium carbonate. Here, we will study the titration of HCl and sodium carbonate in detail.
Aim
Determination of the strength of the diluted hydrochloric acid solution by titrating it against the normal sodium carbonate solution (M/10).
Theory
The hydrochloric acid solution can be titrated using a methyl orange indicator against the sodium carbonate solution. If a slightly acidic solution is titrated with a weak base, the endpoint is slightly acidic. The solution is slightly basic if a weak acid is titrated with a strong base since the salt produced is to a certain degree hydrolyzed. The reaction of sodium carbonate with HCl is given below.
Na2CO3(aq) + 2HCl(aq) → 2NaCl(aq) + CO2(g) + H2O(l)
CO32-(aq) + 2H+(aq) → CO2(g) + H2O(l)
These are the hydrochloric acid and sodium carbonate equations.
In acid-base titrations, the amount of the acid becomes chemically equivalent to the amount of base present. The solution becomes neutral in the event of a strong acid and a strong base titration of the solution.
Materials Required
Burette
Pipette
Conical flask
Burette stand
Funnel
Stirrer
White glazed tile
Measuring flask
Hydrochloric acid
Sodium carbonate
Methyl orange
