What is the concentration of H+ ions at a pH = 11?
natta225 [31]

Answer:

\huge 1 × {10}^{-11} \: \: M

Explanation:

The pH of a solution can be found by using the formula

pH = - log [ {H}^{+} ]

Since we are finding the H+ ions we find the antilog of the pH

So we have

11 =  -  log({H}^{+})  \\ {H}^{+} =  {10}^{ - 11}

We have the final answer as

1 × {10}^{-11} \: \: M

Hope this helps you

Hydrogen chloride gas is dissolved in water to produce a solution of hydrochloric acid.
asambeis [7]

Answer:

Water is a polar solvent

Explanation:

We must know that pure dry hydrogen chloride gas does not show any acidic property.

In fact, when hydrogen chloride is dissolved in water, it breaks up into H3O^+ ions and Cl^- ions. This is possible because water is a polar solvent and assists the ionization of HCl.

In nonpolar solvents such as benzene, hydrogen chloride gas is not ionized hence it does not show any acidic property in a benzene solution.

A solution was prepared by mixing 50.00 ml of 0.100 M of HNO3 and 100.00 ml of 0.200 M HNO3. Calculate the molarity of the final
valentina_108 [34]

Answer:

The molarity of this final solution is 0.167 M

Explanation:

Step 1: Data given

Volume of a 0.100 M HNO3 solution = 50.0 mL

Volume of a 0.200 M HNO3 = 100.0 mL

Step 2: Calculate moles

The final molarity must lie between 0.1M and 0.2M  

Moles = molarity * volume

Moles HNO3 in 50mL of a 0.100M solution = 0.05 L *0.100 M = 0.005 mol

Moles HNO3 in 100mL of a 0.200M solution = 0.100 L*0.200 = 0.020mol

total moles = 0.005+0.020 = 0.025 moles in 150mL solution = 0.150L

Step 3: Calculate molarity of final solution

Molarity = mol / volume

Molarity 0.025 moles /0.150  L

Molarity = 0.167M

The molarity of this final solution is 0.167 M
