# What is the pH of 3M HCl solution?

## What is the pH of 3M HCl solution?

For 10^-3M HCl the [H+] concentration is 0.001, so its pH= 3 .

### What is the pH of M HCl?

pH-values for very strong acids are easy to calculate, because the concentration of H+ (or H3O+) is identical to the concentration of HCl in the solution. Thus, with pH = -log concentration of H+, the 1 M solution of HCl will give the pH of -log 1 or 0 (Zero), because 10 ^0 = 1.

What is the pH of 2.1 m HCl?

The solution prepared by adding one drop of 2 M HCl to 100 mL of water would therefore have a pH of 3.

What is the pH of 1.0 m HCl?

0001 M HCl is the same as saying that 1 *10-4 moles of H+ ions have been added to solution. The -log[. 0001] =4, so the pH of the solution =4.

## What is the pH of 5.0 m HCl?

From this table of activity coefficients 5m HCl has an activity coefficient of 2.38, so activity is 11.9, which yields pH = -1.1.

### What is the pH of 4 m HCl?

How do you find pH with M?

To calculate the pH of an aqueous solution you need to know the concentration of the hydronium ion in moles per liter (molarity). The pH is then calculated using the expression: pH = – log [H3O+].

What is the pH of 0.1 M HF?

3.45
An aqueous solution containing 0.1M HF and 0.1 M KF has a pH of 3.45.

## What is the pH of a 0.00001 molar HCl solution?

– We know that HCl dissolves to give protons and chloride ions. The dissociation reaction in aqueous medium can be given as below. Thus, the pH of the solution will be 8.

### What is the pH of 0.040 M HCl?

4.70
of pap-HCl. 11. A 0.040 M solution of a weak acid (call it HA) has a pH of 4.70. Calculate the Ka and pKa of the acid.

How do you find the pH of 0.0001 M HCl?

pH = – log10[H3O+] pH + pOH = 14.

What is the pH of 4.0 10 − 3 M HCl?

The pH is 2.35.

## How to calculate the pH of 0.3 M HCl solution?

H+ = 0.3 M Substitute the value into the formula Here are some examples of pH Calculation 1. How to Calculate the pH of 0.3M HCL Solution? To Calculate the pH of 0.3M HCL Solution take the negative logarithm of Hydronium Ion Concentration i.e. -log (0.3) and perform basic logarithmic maths to get the pH.

### How much HCl is in a 5.0m NaOH solution?

20.0 mL of a 3.0M HCl solution are mixed with 20.0 mL of a 5.0M NaOH solution. What is the pH? – YouTube 20.0 mL of a 3.0M HCl solution are mixed with 20.0 mL of a 5.0M NaOH solution.

Which is a strong acidic solution HCl or DM-3?

You can see, 0.1 mol dm -3 HCl solution is strong acidic solution because pH value is well below seven. In the lab, there are concentrated HCl bottles. H + concentration is very high in those solution.

What is the pH of a concentrated HCl bottle?

Therefore, pH value of these concentrated HCl bottles are very low values (negative pH values). Concentration of laboratory concentrated HCl bottles is expressed as weight percentage (w/w%) as 36% , 36.5%, 37. Calculate pH of following HCl solution.
