## What is the pOH of a 0.025 M HCl solution?

What is the concentration of [oh-] in a solution of 0.025 m HCL? It’s known that alcalinity is represented by: pOH = -log [OH-]. So, the pOH of that acid solution is 12.4!

## What are the pH and pOH for a 0.025 M KOH solution?

pH = +12.40 and pOH = +1.60.

## How do you find the pOH of a solution?

To find the pOH, simply subtract the pH from 14. In order to calculate the pOH, take the negative log of the hydroxide ion concentration. To find the pH, simply subtract pOH from 14.

## What is the pH of a 0.025 M Oh − solution?

0.94. 1.60.

## What is the pH of a 0.20 M solution of HCl?

That’s important because pH is simply the negative log off the H plus ions. So we have to do is plug in that value. So negative log off 0.20 is going to give us a final answer of 0.7. And that right there represents our pH, and that is our final answer.

## What is the pH of a 0.0075 M solution of HCl?

Thus, the pH of the given hydrochloric acid is 2.1.

## What is the pH of a 0.01 M solution of KOH?

Bases

---|---|---|

0.1 M HCl | 0.1 M | 0.1 |

0.001 M HNO_{3} |
0.001 M | 0.001 |

0.01 M NaOH | 1 x 10^{–}^{12} |

1 x 10^{–}^{5} M KOH |
1 x 10^{–}^{9} |
1 x 10^{–}^{5} |

## What is pOH formula?

To calculate the pOH of a solution you need to know the concentration of the hydroxide ion in moles per liter ( molarity ). The pOH is then calculated using the expression: pOH = – log [OH^{–}] Example: What is the pOH of a solution that has a hydroxide ion concentration of 4.82 x 10^{–}^{5} M?

## What does pOH stand for?

POH

Acronym | Definition |
---|---|

POH | Past Obstetric History |

POH | Pat on Head |

POH | Partial-Order Hold |

POH | Power of Hydroxide (ion value) |

## What is the pOH if the pH is 4?

The pOH Concept Consider a solution with a pH = 4.0. The [H^{+}] of the solution would be 1.0 × 10^{–} ^{4} M. Dividing Kw by this yields a [OH^{−}] of 1.0 × 10^{–}^{10} M. Finally the pOH of the solution equals -log(1.0 × 10^{–}^{10}) = 10.

## How do you find the pH of Ca Oh 2?

Ca ( OH ) 2 is a strong base that dissociates in water to give two OH – ions per formula unit. Thus, the concentration of OH – ions in the solution is 2 x (0.011 M ) = 0.022M. We can calculate the pH of the solution in two equivalent ways.

## What is the pH of 0.0015 m NaOH?

10.0 (2) What is the pH of a 0.0001 M NaOH solution? SOLUTION: Strong base so, pOH = -log[ NaOH ] = -log(0.0004)=-log(1×10-4)=4.0 pH = 14.0-pOH = 14.0 – 4.0 = 10.0 (makes sense since we expect basic solution).

## What is the pH of a.001 M Ca Oh 2?

So,the concentration of OH – ions in the solution is 0.1 M.So pOH is 1 and hence pH is 13.
