What you are doing here is titration. You know you have a solution of HCl, but you do not know how much HCl is in it. For this you use something that can react with HCl (NaOH) and use an indicator to tell you when the reaction is complete. The reaction is pretty simple:
HCl + NaOH --> H2O + NaCl
You can see here that NaOH and HCl have a 1:1 mol relationship. So, lets find out how many moles of NaOH you used up with concentration = moles/volume
0.10 M NaOH = moles NaOH/ 0.0197 L NaOH solution
Remember that M is in moles/L
moles NaOH = 0.00197 moles
Since you have a 1:1 relationship of NaOH with HCl, the 0.00197 mol applies to HCl as well.
The next question works the same way, but backwards. Try doing it yourself if you understood the first part before reading my answer.
Find out how many moles of HCl you have so you can find out how much moles of NaOH you need for the neutralization.
0.050 M HCl = n HCl / 0.020 L HCl soln
n HCl = 0.001 mol HCl
Remeber the 1:1 relationship, which gives you that n NaOH = 0.001 mol. Now all you need is the volume.
0.1 M NaOH = 0.001 mol NaOH/ Volume soln
V = 0.01 L = 10 mL

The acid test that tells whether a mineral is what?
The acid test that tells whether a mineral is calcite or not is performed by placing a drop of dilute hydrochloric acid onto the mineral. Calcite will fizz and release bubbles of carbon dioxide gas when it reacts with the acid.
How do you test hydrochloric acid and magnesium metal?
you put the hydrochloric acid in a test tube then you put the magnesium metal in the test tube with the hydrochloric acid in it then you put a cork on the top ofthe test tube and watch it fizz.
Hydrochloric acid formula and use?
The formula for hydrochloric acid is HCl. It is commonly used in laboratories as a reagent to test the presence of metal carbonates and as a cleaning agent for various applications due to its strong acidic properties.
What does the The acid test tells whether a mineral is?
The acid test is used to determine if a mineral contains calcium carbonate by observing if it fizzes when a weak acid, such as dilute hydrochloric acid, is applied to it. If the mineral fizzes, it indicates the presence of calcium carbonate.
Why can't sulfuric acid be used instead of hydrochloric acid in sulphate test?
Using sulfuric acid in place of hydrochloric acid for a sulfate test can produce inaccurate results due to the formation of insoluble precipitates with some sulfates. This can interfere with the detection of sulfate ions in the test solution. Hydrochloric acid is preferred as it reduces the likelihood of forming these precipitates, ensuring a more reliable sulfate test.

Can concentrated nitric acid be used in flame test instead of concentrated hydrochloric acid?
Cleaning of the test wire (platinum or nickel-chromium alloy) may by realized with nitric acid or hydrochloric acid.Rinsing is made with demineralized water.
What does acid test tell us about a mineral?
The acid test helps determine if a mineral is a carbonate by observing if it produces bubbles when an acid, usually hydrochloric acid, is applied to it. If the mineral fizzes and produces bubbles, it indicates the presence of carbonate minerals such as calcite or dolomite.
Is hydrochloric acid flame test color?
Hydrochloric acid itself does not produce a distinct flame color when burned. However, some metal chlorides formed from the reaction of hydrochloric acid with metals can produce colored flames when burned.
A strip of zinc is dropped into a test tube of hydrochloric acid?
an exothermic reaction
Do hydrochloric acid and silver react?
Silver does not react with hydrochloric acid.
The acid test tells whether a mineral is .?
a carbonate
Which acid you need to use for gold test hydrochloric acid and sulfuric acid?
Hydrochloric acid is typically used for testing gold because it can help dissolve other metals that might be present along with the gold. Sulfuric acid, on the other hand, is not commonly used for testing gold and may not be as effective as hydrochloric acid.
