Answer:

True

Explanation:

Rudik [331]3 years ago
7 0

Answer:

True

Explanation:

This is true because When two or more elements or compounds are blended without combining chemically, you've got a mixture. Each substance in a mixture keeps its own properties, and mixtures can be separated using physical or mechanical means. Solids, liquids and gases can all be blended into mixtures.

Equal volumes of 0.1m naoh and 0.1m hcl are thoroughly mixed. the resulting solution has a ph closest to
son4ous [18]
Lets assume x volume of NaOH and x volume of HCl are added together.
NaOH ---> Na⁺ + OH⁻
NaOH is a strong base therefore it completely ionizes and releases OH⁻ ions into the medium
HCl ---> H⁺ + Cl⁻
HCl is a strong base and completely ionizes and releases H⁺ ions in to the medium. number of NaOH moles in 1 L - 0.1 mol
Therefore in x L - 0.1 /1 * x = 0.1x moles of NaOH present 
Similarly in HCl x L contains - 0.1x moles of HCl
H⁺ + OH⁻ ---> H₂O
Due to complete ionisation, 0.1x moles of H⁺ ions and 0.1x moles of OH⁻ ions react to form 0.1x moles of H₂O. Therefore all H⁺ and OH⁻are completely used up and yield water molecules.
Then at this point the H⁺ and OH⁻ ions in the medium come from the weak dissociation of water. This is equivalent to 1 x 10⁻⁷M
pH = -log [H⁺]
pH = -log [10⁻⁷]
pH = 7
pH is therefore equals to 7 which means the solution is neutral
