krek1111 [17]
Based on the information I would assume B, 73 degrees...

It shouldn't be A, 4 minutes on the burner should increase the temperature.

If it were D, it would be beyond boiling, and water takes a decent amount of energy to heat, D should be all vapor.

Same logic for C, it's basically almost boiling.

I would say 73 degrees seems most reasonable for 4 minutes.

Can someone tell me how to differentiate if a given salt is acidic, basic, or neutral?​
satela [25.4K]

\bold{\huge{\underline{ Solution }}}

<h3><u>Basic </u><u>Characteristic </u><u>of </u><u>acids </u></h3>

  • Acids are sour in taste
  • Acid turns blue litmus paper or solution into red litmus paper or solution
  • Acids are good conductor of electricity because it dissociate into cation in aqueous solution
  • Acids classified into edible acids and non edible acids. Non edible acids are very hazardous
  • Generally, All acids are soluble in water
  • Acids have PH smaller than 7

<u>Arrhenius </u><u>definition </u><u>of </u><u>acids </u><u>:</u><u>-</u>

According to Arrehinus,

  • Acids are those substances which when dissolve in water given H positive ions . Then, this hydrogen ions combine with water to form H30 + ions

<u>Second </u><u>definition </u><u>of </u><u>Acids </u><u>was </u><u>given </u><u>by </u><u>Bonsted </u><u>Lowry </u><u>:</u><u>-</u>

According to Bonsted Lowry

  • Acids are the proton donors that is when acids dissociate into water gives hydrogen ions that is H+ ions

<u>3rd </u><u>definition </u><u>was </u><u>given </u><u>by </u><u>Lewis </u>

According to Lewis

  • Acids are those substances which have the ability to accept a pair of electrons .

Example of Acids

  • HNO3 :- Nitric acid
  • H2SO4 :- Sulfuric acid
  • HCl :- Hydrochloric acid

<h3><u>Basic </u><u>characterists </u><u>of </u><u>bases </u></h3>

  • Bases are bitter in taste
  • Bases turns red litmus paper into blue litmus paper or solution
  • Bases are also good conductor of electricity because on dissociation it produces anion in aqueous solution
  • Bases are also good conductor of electricity
  • When bases are soluble in water then they are known as alkaline base
  • Bases have PH greater than 7

<u>Arrehinus definition of bases :-</u>

According to Arrehinus ,

  • Bases are those substances which when dissolve in water produce OH negative ions that is hydroxide ions

<u>Bonsted Lowry definition </u>

According to Bonsted Lowry

  • Bases are the proton donors as they produce OH negative ions in dissociation in aqueous solution

<u>Lewis </u><u>definition </u>

According to Lewis

  • Acids are those substances which have the ability to lose electrons that is they are electron donors.

Example of bases

  • Ca(OH)2 :- Calcium hydroxide
  • NaOH :- Sodium hydroxide
  • KOH :- Potassium hydroxide

[ Note :- There are so many Lewis acids and bases but they are not Arrhenius or Lowry acids or bases ]

<h3><u>Basic </u><u>characteristic </u><u>of </u><u>salt </u></h3>

  • Salts are the ionic compounds which are composed of acids and bases that cation and anion
  • Salts are generally found in oceans and seas in the forms of crystals
  • As they are composed of acids and bases so they are neutral in nature but the salt of strong acid or weak base is acidic in nature or vice versa
  • Salts are also good conductor of electricity as they form ionic bond
  • Generally, All salts are soluble in water.
  • The PH of common Salt is 7

Example of salts

  • NH4Cl :- Ammonium chloride
  • CuSO4 :- Copper sulphate
  • NaCl :- Sodium chloride

Titration of 0.824 g of potassium hydrogen phthalate required 38.314 g of naoh solution to reach the end point detected by pheno
melamori03 [73]

1.062 mol/kg.

<em>Step 1</em>. Write the balanced equation for the neutralization.

MM = 204.22 40.00

KHC8H4O4 + NaOH → KNaC8H4O4 + H2O

<em>Step 2</em>. Calculate the moles of potassium hydrogen phthalate (KHP)

Moles of KHP = 824 mg KHP × (1 mmol KHP/204.22 mg KHP)

= 4.035 mmol KHP

<em>Step 3</em>. Calculate the moles of NaOH

Moles of NaOH = 4.035 mmol KHP × (1 mmol NaOH/(1 mmol KHP)

= 4.035 mmol NaOH

<em>Step 4</em>. Calculate the mass of the NaOH

Mass of NaOH = 4.035 mmol NaOH × (40.00 mg NaOH/1 mmol NaOH)

= 161 mg NaOH

<em>Step 5</em>. Calculate the mass of the water

Mass of water = mass of solution – mass of NaOH = 38.134 g - 0.161 g

= 37.973 g

<em>Step 6</em>. Calculate the molal concentration of the NaOH

<em>b</em> = moles of NaOH/kg of water = 0.040 35 mol/0.037 973 kg = 1.062 mol/kg
