What happens if you added soduim hydroxide solution to some hydrochloric acid in a beaker?
When sodium hydroxide solution is added to hydrochloric acid in a beaker, a chemical reaction occurs, resulting in the formation of water and sodium chloride salt. This reaction is exothermic, meaning it releases heat energy. The pH of the resulting solution will increase due to the presence of sodium hydroxide, which is a strong base.
What else can I help you with?
When you mix a few drops of phenolphthalein solution to a beaker of pure water mixed with calcium hydroxide what happens?
The phenolphthalein solution will turn pink in the presence of the basic calcium hydroxide solution. This color change indicates the presence of a base. This reaction is commonly used as an indicator for determining the endpoint in acid-base titrations.
If A scientist pours 3.48 ML of hydrochloric acid into a beaker How many liters of hydrochloric acid did the scientist pour into the beaker?
The scientist poured 0.00348 liters of hydrochloric acid into the beaker.
How you would prepare a sample of solid sodium chloride from sodium hydroxide solution and hydrochloric acid?
Add concentrated solution of Hydro chloric acid to the solution of sodium hydroxide till mixture becomes neutral (checked by litmus) then heat the mixture , when a little amount of water is left allow to cool the mixture , the crystals of sodium chloride settelted down filter and dry the crystals.
Which salt will be made if hydrochloric acid is added to the beaker?
If hydrochloric acid is added to a beaker, the salt formed will depend on the other reactant present. For example, if sodium hydroxide is also present, sodium chloride (table salt) will be formed. The specific salt formed will depend on the combination of the acid and base used in the reaction.
Why is it important to let the sand settle first at the bottom of the beaker before pouring the solution into another beaker?
Letting the sand settle at the bottom of the beaker helps separate it from the solution, reducing the risk of contaminating the solution with sand particles. This step allows for cleaner and more accurate transfer of the solution into another beaker for further processing or analysis.
What happens to the concentration of sodium hydroxide solution when it is left in beaker?
If left in an open beaker, the concentration of sodium hydroxide solution may decrease due to evaporation of water. If left in a closed beaker, the concentration should remain constant unless there is some chemical reaction occurring.

The phenolphthalein solution will turn pink in the presence of the basic calcium hydroxide solution. This color change indicates the presence of a base. This reaction is commonly used as an indicator for determining the endpoint in acid-base titrations.
What happens when a strip of red litmus is immersed in a beaker containing 10% sodium hydroxide?

What would be the effect of placing the standard sodium hydroxide in a beaker which contained some residual water in the breaker?
The standar solution is now falsified.
Gerald's science teacher mixed room temperature samples of hydrochloric acid and sodium hydroxide in a large beaker. The solution still looked clear like water but when the students carefully touched?
Mixing correct amounts of hydrochloric acid (HCL) and sodium hydroxide (NaOH) gives you water (H2O) and table salt (NaCl). If done properly, the mixture would be harmless and if tasted, would taste salty. In a classroom, it should not be touched nor tasted unless first insuring that it is neither too acidic or alkaline, unless the teacher does it first to show it does no harm.
Is it important to dry a beaker before collecting a solution?
Yes, it is important to dry a beaker before collecting a solution as any remaining liquid in the beaker could dilute the solution being collected, affecting the concentration and accuracy of the solution. Drying the beaker also helps to ensure that the solution is not contaminated by any residual water or impurities from the beaker.
Why does the mass of a beaker containing magnesium and hydrochloric acid go down during the reaction?
The mass of the beaker decreases during the reaction between magnesium and hydrochloric acid because hydrogen gas is produced as a byproduct. When magnesium reacts with hydrochloric acid, it forms magnesium chloride and releases hydrogen gas, which escapes into the atmosphere. Since the gas is not contained within the beaker, the total mass of the system decreases as the reaction proceeds.
If A beaker contains 100 grams of 1.7 M NaCl and you transfer 50 grams what is the molarity of the solution in the beaker?
After transferring 50 grams of the 1.7 M NaCl solution to a new beaker, the final amount of NaCl in the original beaker will be 50 grams. To find the new molarity, you would first calculate the new moles of NaCl in the beaker, then divide by the total volume of the solution in liters. The molarity will be reduced in the original beaker due to the dilution from transferring a portion of the solution.
Why is it important to let the sand settle first at the bottom of the beaker before pouring the solution into another beaker?
Letting the sand settle at the bottom of the beaker helps separate it from the solution, reducing the risk of contaminating the solution with sand particles. This step allows for cleaner and more accurate transfer of the solution into another beaker for further processing or analysis.
