Answer:
Explanation:
by using litmus papaer it will turn into red if solutions is acidic
and into blue if it's basic
by using Magnesium ribbon. Magnesium do not react with bases so hydrogen gas will produce when Magnesium is dipped in an acidic solution
The molar mass of H2O2 is 34 g/mol.
Answer:
Explanation:
KHT is a salt which ionises in water as follows
KHT ⇄ K⁺ + HT⁻
Solubility product Kw= [ K⁺ ] [ HT⁻ ]
product of concentration of K⁺ and HT⁻ in water
In KCl solution , the solubility product of KHT will be decreased .
In KCl solution , there is already presence of K⁺ ion in the solution . So
in the equation
[ K⁺ ] [ HT⁻ ] = constant
when K⁺ increases [ HT⁻ ] decreases . Hence less of KHT dissociates due to which its solubility decreases . It is called common ion effect . It is so because here the presence of common ion that is K⁺ in both salt to be dissolved and in solvent , results in decrease of solubility of the salt .
For emission n=3 to n=1 The energy will be released
When an electron transitions from a lower state of energy energy level, absorption spectra are formed. When an electron transitions from a higher energy state to a lower energy state, emission spectra are produced.
To see a wavelength released, electrons would have to go down energy levels to view an emission spectra, limiting our solution options to And because n=3 to n=1 has more energy emitted than n=2 to n=1, the one with more energy emitted will have a shorter wavelength because wavelength and energy are inversely related. Energy will be released as an electron transitions from a higher energy state 3 to a low energy state 1.

<span>In my opinion, it is a rotten question, phrased as it is. It all depends on how much acid and how much base. It also depends on the type of acid (sulfuric acid reacts differently than hydrochloric - sulfuric has two atoms of hydrogen compared to hydrochloric which has one atom of hydrogen per molecule). It also can depend on the concentration - for example, if you're mixing a one molar solution of acid with a two molar solution of base, and on how much you are mixing - if you are mixing one liter of base with one liter of acid, or whatever. Your instructor needs to establish these things in order to make it a question you can actually answer.
But, your instructor probably means what happens if you add the same amount of an acid and a base together, and they have the same strength. Ideally, if you mix the same amounts of an acid and a base, and the acid has one atom of hydrogen, then you would get water plus a salt, which would have a neutral pH.
For example, HCl + NaOH, mixed in the same amounts and at the same concentrations would give you HOH (or water) plus NaCl (which is actually table salt). All acids and bases that are mixed in these equal concentrations always give you water plus a salt (although not always table salt - just what is chemically known as a "salt).</span>
