Which best describes how a pH test strip works?

Chemistry
2 answers:
Vikki [24]3 years ago
6 0

Answer: Option (A) is the correct answer.

Explanation:

A pH strip is a strip which helps in determining whether a solution is acidic or basic in nature.

That is, if a solution is acidic in nature then a pH strip will change from blue to red. Whereas when a solution is basic in nature then a pH strip will change from red to blue.

Thus, we can conclude that statement molecules in the paper react differently with hydronium and hydroxide ions, best describes how a pH test strip works.

Molecules in the paper react differently with Hydronium and Hydroxide.

pH paper deals with acidity and basicity of something.  You are correct in thinking that A is the answer. Always go with your gut. don't be like me when I was in college who always second guessed my answers. Good luck with chemistry.

How was president Andrew Jackson wrong for closing the bank
Paladinen [302]
Jackson, the epitome of the frontiersman, resented the bank's lack of funding for expansion into the unsettled Western territories. Jackson also objected to the bank's unusual political and economic power and to the lack of congressional oversight over its business dealings.

Calculate the equilibrium number of vacancies per cubic meter for copper at 1000K. The energy for vacancy formation is 0.9eV/ato
nexus9112 [7]

Answer:

Therefore the equilibrium number of vacancies per unit cubic meter =2.34×10²⁴ vacancies/ mole

Explanation:

The equilibrium number of of vacancies is denoted by N_v.

It is depends on

  • total no. of atomic number(N)
  • energy required for vacancy
  • Boltzmann's constant (k)= 8.62×10⁻⁵ev K⁻¹
  • temperature (T).

N_v=Ne^{-\frac{Q_v}{kT} }

To find  equilibrium number of of vacancies we have find N.

N=\frac{N_A\ \rho}{A_{cu}}

Here ρ= 8.45 g/cm³  =8.45 ×10⁶m³

N_A= Avogadro Number = 6.023×10²³

A_{Cu}= 63.5 g/mole

N=\frac{6.023\times 10^{23}\times 8.45\times 10^{6}}{63.5}

   =8.01\times 10^{28 g/mole

Here Q_v=0.9 ev/atom , T= 1000k

Therefore the equilibrium number of vacancies per unit cubic meter,

N_v=( 8.01\times 10^{28}) e^{-(\frac{0.9}{8.62\times10^{-5}\times 1000})

   =2.34×10²⁴ vacancies/ mole

What controls flowering in many<br> plants?
katrin2010 [14]

Answer:

All flowering is regulated by the integration of environmental cues into an internal sequence of processes. These processes regulate the ability of plant organs to produce and respond to an array of signals. The numerous regulatory switches permit precise control over the time of flowering.
