If 25mL of 3.0M HCl is added to 435mL of water, what is the concentration of HCl

When all the water is evaporated from a sodium hydroxide solution, solid sodium hydroxide is obtained. However, if you evaporate the water in an ammonium hydroxide solution, you will not produce solid ammonium hydroxide. Explain why. What will remain after the Water is evaporated?

Four different substances of the generalized formula HA were dissolved in water, with the results shown in the diagrams. Which of the diagrams represents the substance that is the strongest electrolyte?

Write a balanced chemical equation that represents the self-ionization of water.

Classify the solutions represented in Exercises 9.28 and 9.30 as acidic, basic, or neutral.

A scientist has synthesized a diprotic organic acid, H2A, with a molar mass of 124.0 g/mol. The acid must be neutralized (forming the potassium salt) for an important experiment. Calculate the volume of 0.221 M KOH that is needed to neutralize 24.93 g of the acid, forming K2A.

In Arrhenius acidbase theory, what ion is responsible for the properties of a. acidic solutions b. basic solutions

Classify each of the following compounds as a strong electrolyte or a weak electrolyte. a. H3PO4 b. HNO3 c. KNO3 d. NaOH

A Liquid HF undergoes an autoionization reaction: 2HFH2F++F (a) Is KF an acid or a base in this solvent? (b) Perchloric acid, HCIO4, is a strong acid in liquid HF. Write the chemical equation for the ionization reaction. (c) Ammonia is a strong base in this solvent. Write the chemical equation for the ionization reaction. (d) Write the net ionic equation for the neutralization of perchloric acid with ammonia in this solvent.

You purchase a bottle of water. On checking its pH, you find that it is not neutral, as you might have expected. Instead, it is slightly acidic. Why?
